Looking at this again I think the test is actually broken. It tries to
check whether fb_set_base correclty waits for any outstanding flips (well,
it can't really check that, but it should exercise the code at least). So
the right place to call this is actually right _after_ issueing the flip,
where the TEST_DPMS and TEST_MODESET cases are.
