If we failed to create a native texture from pixmap via EGL or GLX then we shouldn't call the winsys's texture_pixmap_x11_damage_notify function. By doing the validation in cogl-texture-pixmap-x11.c the winsys code can continue to assume that it doesn't need to verify there is a valid tex_pixmap->winsys pointer. Thanks to Damien Leone <dleone@nvidia.com> for catching this issue. https://bugzilla.gnome.org/show_bug.cgi?id=660184
