[Abdiel Janulgue]

Add test that makes sure RS bit only gets executed on BDW and
on the render ring.

See Chris comment, but 0 is actually _not_ an invalid ring, but aliases
RCS. Yeah, we have a fun api. So this should actually suceed, at least on
bdw (and -EINVAL everywhere else).

So you need to explicitly test with some other ring like VCS
(I915_EXEC_BSD).

Also you didn't update the invalid-flag subtest ... I wonder why that
didn't fail on bdw.
