drm/i915: Eliminate one more frequent drm_format_info()
Another (somewhat expensive) drm_format_info() call has
appeared in intel_plane_can_async_flip(). That one may get
called several times per commit so we need to get rid of
it.
Fortunately most callers already have the framebuffer at
hand, so we can just grab the format info from there.
The one exception is intel_plane_format_mod_supported_async()
where we have to do the lookup. But that only gets called
(a bunch of times) during driver init to build the
IN_FORMATS_ASYNC blob, and afterwards there is no runtime
cost.
