scsi: ILLEGAL REQUEST + ASC==27 => target failure
ASC 0x27 is "WRITE PROTECTED". This error code is returned e.g. by Fujitsu ETERNUS systems under certain conditions for WRITE SAME 16 commands with UNMAP bit set. It should not be treated as a path error. In general, it makes sense to assume that being write protected is a target rather than a path property.
