staging: drm/imx: ipuv3-crtc: immediately update crtc->fb in ipu_page_flip
Since commit 8cf1e9811471f2910fa38dc1b28e1789080ba961 ("drm: Add consistency check for page-flipping") drm_mode_page_flip_ioctl contains a WARN_ON that triggers if the .page_flip callback didn't update the crtc->fb pointer to the new framebuffer immediately.
