cogl/context: Report error if allocating fallback texture failed

Browse Source 
Error out if we fail to allocate the 1x1 all white fallback texture. If
we don't do this, and instead continue, any future (likely) allocation
failure will end up in obscure places that assumes the fallback texture
exists.
