drm: rcar-du: Handle event when disabling CRTCs
The driver currently handles vblank events only when updating planes on
a CRTC. The atomic update API however allows requesting an event when
disabling a CRTC. This currently leads to event objects being leaked in
the kernel and to events not being sent out. Fix it.
