drm/nouveau/fbcon: fix NULL pointer access in nouveau_fbcon_destroy

Browse source

When the fbcon object is initialized, but nouveau_fbcon_create is not
called, we run into a NULL pointer access within nouveau_fbcon_create when
unloading nouveau.

The call to drm_fb_helper_funcs.fb_probe is deferred until there is a
display for real since 4.14, that's why fbcon->helper.fb is still not set.
