Simon McVittie e339a57ddf cogl: Defend against empty or unallocated framebuffers 
It isn't immediately obvious that this is impossible, because there's some
"action at a distance" going on with framebuffers that have their size
set lazily, after their textures get allocated; so let's make this a
critical warning rather than crashing.

In particular, this works around a crash when gnome-shell tries to blur a
background that hasn't yet had any space allocated for it - which it seems
is really an actor layout bug, but more robustness seems good to have.

Workaround for <https://gitlab.gnome.org/GNOME/gnome-shell/-/issues/2538>.
