[SCSI] Deprecate SCSI_PROT_*_CONVERT operations
The checksum format is orthogonal to whether the protection information is being passed on beyond the HBA or not. It is perfectly valid to use a non-T10 CRC with WRITE_STRIP and READ_INSERT. Consequently it no longer makes sense to explicitly refer to the conversion in the protection operation. Update sd_dif and lpfc accordingly. Signed-off-by: Martin K.
