Skip 0-block WRITE SAME tests for targets that don't support these operations, ie. they have write_same_no_zero (WSNZ) set in the block limits vpd. Also, fix the test: "Test WRITESAME10 of 1-256 blocks at the end of the LUN by setting number-of-blocks==0" to actually pass 0 blocks instead of the number of remaining blocks to the end.
