***SPAM*** [ofa-general] [PATCH v4] fix local port smlid

[Eli Dorfman (Voltaire)]

fix local port smlid

when opensm goes from master to standby due to handover its local
port smlid will be wrong (equal to its own lid).
the new master opensm will change smlid only after local sm
(previous master) is in standby and will not query its port again.
