staging: drm/imx: ipuv3-crtc: immediately update crtc->fb in ipu_page_flip

Browse source 
Since commit 8cf1e98114
("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.
