TESTS: Fix all 0block tests

Browse Source 
Remove the test for accessing 0blocks (transfer length==0) at the end of the device since they were invalid.

SBC says that :
   If the LBA plus the transfer length exceeds the capacity
   of the medium, then the device server shall terminate the
   command with CHECK CONDITION status with the sense key
   set to ILLEGAL REQUEST and the additional sense code
   set to LOGICAL BLOCK ADDRESS OUT OF RANGE.

This means that if TL==0  then a LBA that is the first LBA beyond the end of
device is actually valid.

Improve output for error conditions and harminize all tests
