scsi: qla2xxx: Fix recursion while sending terminate exchange
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 82de802ad46e ("scsi: qla2xxx: Preparation for Target MQ.")
