test_writesame*_0blocks: skip 0-block test if unsupported

Browse Source 
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.
