backend/drm: fix segfault in page_flip_handler
Since 5b1b43c68c7a ("backend/drm: make wlr_drm_plane.{pending,queued,current}_fb
pointers"), current_fb can be NULL if there's no buffer. If current_fb
is not NULL, current_fb->wlr_buf is guaranteed to not be NULL.
Closes: https://github.com/swaywm/wlroots/issues/2634
