[igt-dev] [PATCH i-g-t] igt/kms_universal_plane: Flush pending cleanups

[Chris Wilson]

drm_atomic_helper allows for up to one outstanding cleanup task to be in
flight before a new modeset (see stall_commit in stall_checks()), In
lieu of hooking up a debugfs to force flushing of the outstanding work,
submit enough blocking modesets to ensure that the pending work is
completed before continuing.
