Shenghao Yang dc2d5ddb19 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.
