amfd: do not send duplicate removal of assignment, N-Way model [#2022]
AMFD asserted during lock operation on NG when its nodes are deplyed
with
N-WAY model application.
When lock on NG operation is issued, AMFD sends quiesced state to
active SIs
in all the three SUs. Responses for SU2 and SU3 comes and AMFD sends SU
level deletion to them. SU2 contains standby assignment of SI1 which is
still getting quiesced in SU1. Now SU1 faults with su-failover recovery
when
SU2 is still not responded for deletion of assignments. AMFD tries to
perform recovery of SU1 and tries to fail-over SI1 of SU1 but could not
find
any valid standby in any other SU. Since failover is not possible, AMFD
tries to delete all standby assignments of SI1. AMFD tries to send
deletion
for SI1 to SU2 for which SU level deletion is already sent and it
asserts.
Patch avoids sending duplicate deletion of assignments.

Reviewer Checklist:
-------------------
[Submitters: make sure that your review doesn't trigger any checkmarks!]
Your checkin has not passed review because (see checked entries):
___ Your RR template is generally incomplete; it has too many blank entries
that need proper data filled in.
___ You have failed to nominate the proper persons for review and push.
___ Your patches do not have proper short+long header
___ You have grammar/spelling in your header that is unacceptable.
___ You have exceeded a sensible line length in your headers/comments/text.
___ You have failed to put in a proper Trac Ticket # into your commits.
___ You have incorrectly put/left internal data in your comments/files
(i.e. internal bug tracking tool IDs, product names etc)
___ You have not given any evidence of testing beyond basic build tests.
Demonstrate some level of runtime or other sanity testing.
___ You have ^M present in some of your files. These have to be removed.
___ You have needlessly changed whitespace or added whitespace crimes
like trailing spaces, or spaces before tabs.
___ You have mixed real technical changes with whitespace and other
cosmetic code cleanup changes. These have to be separate commits.
___ You need to refactor your submission into logical chunks; there is
too much content into a single commit.
___ You have extraneous garbage in your review (merge commits etc)
___ You have giant attachments which should never have been sent;
Instead you should place your content in a public tree to be pulled.
___ You have too many commits attached to an e-mail; resend as threaded
commits, or place in a public tree for a pull.
___ You have resent this content multiple times without a clear indication
of what has changed between each re-send.
___ You have failed to adequately and individually address all of the
comments and change requests that were proposed in the initial review.
___ You have a misconfigured ~/.hgrc file (i.e. username, email etc)
___ Your computer have a badly configured date and time; confusing the
the threaded patch review.
___ Your changes affect IPC mechanism, and you don't present any results
for in-service upgradability test.
___ Your changes affect user manual and documentation, your patch series
do not contain the patch that updates the Doxygen manual.
