From: Martin Wilck <mwilck@xxxxxxxx>
Since 45235022da99, the firmware is shut down early in the controller
shutdown process. This causes commands sent to the firmware (such as LOGO)
to hang forever. Eventually one or more timeouts will be triggered.
Move the stopping of the firmware until after sessions have terminated.
Fixes: 45235022da99 ("scsi: qla2xxx: Fix driver unload by shutting down chip")
