drm/vc4: Fix a couple error codes in vc4_cl_lookup_bos()

commit b2cdeb19f16ad984eb5bb9193f793d05a8101511 upstream.

If the allocation fails the current code returns success.  If
copy_from_user() fails it returns the number of bytes remaining instead
of -EFAULT.

Fixes: d5b1a78a772f ("drm/vc4: Add support for drawing 3D frames.")
