[SCSI] zfcp: Introduce experimental support for DIF/DIX
Introduce support for DIF/DIX in zfcp: Report the capabilities for the Scsi_host, map the protection data when issuing I/O requests and handle the new error codes. Also add the fsf data_direction field to the hba trace, it is useful information for debugging in that area. This is an EXPERIMENTAL feature for now.
