drm/vc4: Match drm_dev_enter and exit calls in vc4_hvs_atomic_flush
[ Upstream commit 6b0bd1b02ea24b10522c92b2503981970b26d1a2 ]
Commit 92c17d16476c ("drm/vc4: hvs: Ignore atomic_flush if we're disabled")
added a path which returned early without having called drm_dev_exit.
Ensure all paths call drm_dev_exit.
