drm/amdgpu/vcn: fix unitialized variable warnings

Browse source

Avoid returning an uninitialized value if we never enter the loop.
This case should never be hit in practice, but returning 0 doesn't
hurt.

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

v2: - fixed typos in commit message (Alex)
    - use "return 0;" before the done label instead of initializing
      r to 0
