[cogl/wip/rib/introspection: 3/14] Fix _COGL_RETURN_VAL_IF_FAIL return type warning

    Fix _COGL_RETURN_VAL_IF_FAIL return type warning
    
    This fixes a warning by making the _COGL_RETURN_VAL_IF_FAIL check in
    _cogl_offscreen_gl_allocate return FALSE not NULL, since the api returns
    a CoglBool not a pointer.
