Laurence Oberman b9f85b1d32 qla2xxx: fix race in handling rport deletion during recovery causes panic 
When we have an rport disconnect we race during rport deletion and
re-connection resulting in a panic.  When we do this, we call
fc_remote_port_del() just before we do the calls to re-establish the
session with the FC transport with fc_remote_port_add() and then
fc_remote_port_rolechg().

If we remove the call to fc_remote_port_del() before re-establishing
the connection this prevents the race.  This patch has resolved this
for multiple customers via test kernels.

Suggested by Chad Dupuis, implemented and tested by Laurence Oberman.
