I was doing some large lun count testing with 2.6.31 and hit
a BUG_ON() in fc_timeout_deleted_rport(), and it seems like it
should have been just a matter of time before someone did.
It seems invalid to set port_state under lock, then expect it to
remain set after releasing the lock. Another thread called
fc_remote_port_add() when the lock was released, changing the
port_state.
This patch removes the BUG_ON and moves the test of the
port_state to inside the host_lock. It's been running for
several weeks now with no ill effect.
