scsi: qla2xxx: Fix recursion while sending terminate exchange

commit 3efc31f7 upstream.

During error test case where switch port status is toggled from enable to
disable, following stack trace is seen which indicates recursion trying to
send terminate exchange.  This regression was introduced by commit
82de802a ("scsi: qla2xxx: Preparation for Target MQ.")
