qla2xxx: Correct inadvertent loop state transitions during port-update handling.
commit 58b48576966ed0afd3f63ef17480ec12748a7119 upstream.
Transitioning to a LOOP_UPDATE loop-state could cause the driver
to miss normal link/target processing. LOOP_UPDATE is a crufty
artifact leftover from at time the driver performed it's own
internal command-queuing. Safely remove this state.
