[SCSI] mpt2sas: Change in MPI2_RAID_ACTION_SYSTEM_SHUTDOWN_INITIATED notification methodology
The intent of this patch is to perform a graceful shutdown of target drives even if
volume doesn't exits. Changes done in this patch
1. Removed the check for the presence of volumes before sending down
MPI2_RAID_ACTION_SYSTEM_SHUTDOWN_INITIATED. Therefore, this RAID action
would be sent if the card is IR Firmware.
2. The MPI2_RAID_ACTION_SYSTEM_SHUTDOWN_INITIATED is sent even when the
system undergoes suspend (in addition to remove/shutdown which was already
present)
