drm/mediatek: Fix dereference before null check

Null-checking state suggests that it may be null, but it has already
been dereferenced on drm_atomic_get_new_plane_state(state, plane).

The parameter state will never be NULL currently, so just remove the
state is NULL flow in this function.

Fixes: 5ddb0bd4ddc3 ("drm/atomic: Pass the full state to planes async atomic check and update")
