drm/gud: fix NULL fb and crtc dereferences on USB disconnect
On disconnect drm_atomic_helper_disable_all() is called which
sets both the fb and crtc for a plane to NULL before invoking a commit.
This causes a kernel oops on every display disconnect.
Add guards for those dereferences.
Cc: <stable@vger.kernel.org> # 6.18.x
Fixes: 73cfd166e045 ("drm/gud: Replace simple display pipe with DRM atomic helpers")
