[cogl] Don't allow calling cogl_set_source_texture with an INVALID_HANDLE

Browse Source 
Although the underlying materials should allow layers with INVALID_HANDLES
it shouldn't be necissary to expose that via cogl_set_source_texture() and
it's easier to resolve a warning/crash here than odd artefacts/crashes later
in the pipeline.
