John Garry 6472cfb418 scsi: pm8001: Use sas_task_find_rq() for tagging
The request associated with a SCSI command coming from the block layer has
a unique tag, so use that when possible for getting a CCB.

Unfortunately we don't support reserved commands in the SCSI midlayer yet,
so in the interim continue to manage those tags internally (along with
tags for private commands).
