onscreen/native: Add missing error messages

Browse Source 
g_set_error_literal() asserts that the provided message is not NULL.
If it is NULL, the function is entirely no-op.

This resulted in a NULL dereference of the GError, which remained
NULL in this case, when trying to print a warning in
clutter_stage_cogl_redraw_view().
