Proposed fix:
amfnd: do not refresh opensaf components
If an OpenSAF component requires reload after an upgrade,
then AMF should also be upgraded, requiring a node
reboot.
The patch fixes a problem where OpenSAF has been upgraded
and is about to be rebooted. Before the reboot occurs,
IMMND aborts due to message loss, and AMFND is trying to
reload IMMND's configuration. Since IMMND is down, AMFND
is stuck in saImmOmInitialize(), before eventually being killed
by the AMF watchdog.

Normally, amfnd is able to handle immnd restarting.
However, if immnd fails after OpenSAF is upgraded but before the node is
rebooted, then amfnd will 'deadlock' trying to reload immnd's configuration but
immnd is not available!
