drm/vc4: Fix oops when userspace hands in a bad BO.
We'd end up NULL pointer dereferencing because we didn't take the error path out in the parent. Fixes igt vc4_lookup_fail test. Signed-off-by: Eric Anholt <eric@anholt.net> Fixes: d5b1a78a772f ("drm/vc4: Add support for drawing 3D frames.") Cc: stable@vger.kernel.org
