[Intel-gfx] [PATCH igt v4 09/13] igt/gem_exec_parse: update bitmasks test for v >=8

[Robert Bragg]

With v8 of the command parser (where we won't get an EINVAL for an
access violation) this updates the bitmasks test to explicitly confirm
that the command became a NOOP by reading back from where the QW_WRITE
would have otherwise landed.
