scsi: mpt3sas: Stop fw fault watchdog work item during system shutdown

During system shutdown or reboot, mpt3sas will reset the firmware back to
ready state. However, the driver leaves running a watchdog work item
intended to keep the firmware in operational state. This causes a second,
unneeded reset on shutdown and moves the firmware back to operational
instead of in ready state as intended. And if the mpt3sas_fwfault_debug
module parameter is set, this extra reset also panics the system.

mpt3sas's scsih_shutdown needs to stop the watchdog before resetting the
firmware back to ready state.
