Some implementations may send oversized data coming back from Inquiry.
Warn about this instead of failing the test but then perform additional
checks that the padding MUST be zero or else fail the test.

This is the maximum possible size of this page.
Previouslly we only read the arbitrary 255 bytes of page, but for targets
that return >255 bytes of data this would then incorrectly make the test fail
since the data-in buffer was truncated and thus the inq->additional_length
no longer matched up with the datain buffer size.
Now reading up to 260 bytes will avoid the datain buffer from ever becomming truncated, and as a second feature also make sure to test that the target
understands > 8-bit values for the allocation length in the request.
