Sitsofe Wheeler b908bdeb99 Tests: WRITESAME 0-blocks fixes and improvements ...

The current WRITE SAME (WS) 0 blocks test at LBA 0 isn't always correct
because if:
- The target's WSNZ bit set is 0
- The target's MAXIMUM WRITE SAME LENGTH (MWSL) is greater than 0
- We are issuing a WS with a NUMBER OF LOGICAL BLOCKS of 0

then whether the command should return success or failure depends on
whether the starting LBA is within MWSL blocks of the end of the LUN
(see http://www.t10.org/pipermail/t10/2016-May/017988.html for details).

Replace the vestigial code which tried to handle this (but no longer
worked since commit 8585e4509b ) and add
some additional MAXIMUM WRITE SAME LENGTH tests.
