target/sbc: Seperate WRITE_SAME based on UNMAP flag in sbc_ops
This patch adds a new sbc_ops->execute_write_same_unmap() caller for use with WRITE_SAME w/ UNMAP=1, and performs the ->execute_cmd() setup based this bit within sbc_setup_write_same() code. Also, makes the changes in sbc_parse_cdb() to handle a sense_reason_t return from sbc_setup_write_same() on error. Reported-by: Christoph Hellwig <hch@lst.de> Cc: Martin K. Petersen <martin.petersen@oracle.com> Signed-off-by: Nicholas Bellinger <nab@linux-iscsi.org>
