target: Fix WRITE_SAME_[16,32] number of blocks=0 case
This patch fixes the handling of WRITE_SAME_[16,32] emulation where a WRITE_SAME_* CDB with number of blocks=0 was being rejected by SCSI expected data transfer length overflow checking in target core. It changes both CDB cases in transport_generic_cmd_sequencer() to use dev->se_sub_dev->se_dev_attrib.block_size to match what sg_write_same is sending us with --num=0. It also fixes target_emulate_write_same() to properly determine the num_blocks with --num=0 case to determine the remaining range for dev->transport->do_discard().
