scsi: Move sd_pr_type to scsi_common
LIO is going to want to do the same block to/from SCSI pr types as sd.c
so this moves the sd_pr_type helper to scsi_common and renames it. The
next patch will then also add a helper to go from the SCSI value to the
block one for use with PERSISTENT_RESERVE_IN commands.
