Subject: [PATCH 4.19 38/63] scsi: qla2xxx: Turn off IOCB timeout timer on IOCB completion

From: Quinn Tran <quinn.tran@...ium.com>

[ Upstream commit e112761a4f1dcbe9fb9f43f46de7be69d6963b0d ]

Turn off IOCB timeout timer on IOCB completion instead of turning it off in a
deferred task.  This prevent false alarm if the deferred task is stalled out.
