[PATCH] drm/amdgpu/vcn: fix unitialized variable warnings

[Pierre-Eric Pelloux-Prayer]

Init r to 0 to avoid returning an uninitialized value if we never
enter the loop. This case should never be hit in practive, but
returning 0 doesn't hurt.

The same fix is applied to the 4 places using the same pattern.
