drm/amdgpu: Use unsigned ring indices in amdgpu_queue_mgr_map

This matches the corresponding UAPI fields. Treating the ring index as
signed could result in accessing random unrelated memory if the MSB was
set.

Fixes: effd924d ("drm/amdgpu: untie user ring ids from kernel ring
                      ids v6")
