I don't think this function can ever be useful, because you closed the
fd in igt_display_commit_atomic already.
If there's no user for this, I'd drop it for now. If we expect someone
to want to call this, then that same someone probably wants to do the
waiting themselves which doesn't mesh will with the wait/close in
igt_display_commit_atomic.
