[Why]
The type of 'r' is uint32_t and the return codes for both:
- reservation_object_wait_timeout_rcu
- amdgpu_bo_reserve
...are signed. While it works for the latter since the check is
done on != 0 it doesn't work for the former since we check <= 0.
[How]
Make 'r' a long in commit planes so we're not doing any unsigned/signed
conversion here in the first place.
v2: use long instead of int (Christian)
