scsi: smartpqi: Correct driver removal with HBA disks

Browse source

Correct rmmod hangs when using HBA disks with write cache enabled.

Do not set controller flag "in_shutdown" during rmmod. SCSI SYNCHRONIZE
CACHE(10) and SCSI SYNCHRONIZE CACHE(16) requests were blocked with
SCSI_MLQUEUE_HOST_BUSY.
