[cogl] Don't endlessly print the same warning regarding layer fallbacks

Browse Source 
There are various constraints for when we can support multi-texturing and
when they can't be met we try and print a clear warning explaining why the
operation isn't supported, but we shouldn't endlessly repeat the warning for
every primitive of every frame. This patch fixes that.
