[SCSI] ipr: Runtime reset
Some IPR RAID adapter will automatically create single device RAID arrays
for all attached devices when the card is initialized. Setting the
RUNTIME_RESET doorbell bit will prevent this from occurring, since we
only want this behavior the first time the card is initialized and not
each time the card happens to get reset.
