drm/komeda: return early if drm_universal_plane_init() fails.
If drm_universal_plane_init() fails early we jump to the common cleanup code
that calls komeda_plane_destroy() which in turn could access the uninitalised
drm_plane and crash. Return early if an error is detected without going through
the common code.
