GPU reset will drop all flips that are still in the ring. So after the
reset, call update_plane() for all CRTCs to make sure the primary
planes are scanning out from the correct buffer.
Also finish all pending flips. That means user space will get its
page flip events and won't get stuck waiting for them.
v2: Explicitly finish page flips instead of relying on FLIP_DONE
interrupt being generated by the base address update.
v3: Make two loops over crtcs to avoid deadlocks with the crtc mutex
