scsi: mpt3sas: always use first reserved smid for ioctl passthrough

Browse source

ioctl passthrough commands require a SCSIIO smid, but cannot easily
integrate with the block layer. But the driver already has reserved some
SCSIIO smids and we're only ever allowing one ioctl command at a time we
can use the first reserved smid for ioctl commands.
