target: Add generation of LOGICAL BLOCK ADDRESS OUT OF RANGE
commit e2397c704429025bc6b331a970f699e52f34283e upstream.
Many SCSI commands are defined to return a CHECK CONDITION / ILLEGAL
REQUEST with ASC set to LOGICAL BLOCK ADDRESS OUT OF RANGE if the
initiator sends a command that accesses a too-big LBA. Add an enum
value and case entries so that target code can return this status.
