Before this patch, if multiple BO_HANDLES chunks were submitted,
the error -EINVAL would be correctly set but could be overwritten
by the return value from amdgpu_cs_p1_bo_handles(). This patch
ensures that if there are multiple BO_HANDLES, we stop.

@Pierre-Eric can you pick that one up and push to amd-staging-drm-next?
Alex is currently on XDC and I'm a bit busy as well.
Thanks,
