imm: Dont allow standby IMMD to send fevs if active IMMD is still up
[#2029]
During node shutdown, if active IMMD is down before IMMND, the IMMD will
fail to broadcast discard node message to other IMMNDs.
In this case, standby IMMD will help broadcast the discard messages.
But it
should only do that when the active IMMD is really down (immd_remote_up
is
false) or when it becomes active (invoking immd_pending_discards in
rda/amf
callbacks).
This is to prevent the active IMMD and standby IMMD from sending the
discard
messages with different number which cause fevs message loss.

___ 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

___ 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.

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
