drm/amdgpu: prepare the output buffer for GET_PEER_LINKS command

Browse source

Per the xgmi ta implementation, KGD needs to fill in node_ids
in concern into the shared command output buffer rather than the
command input buffer.

Input buffer is not used for GET_PEER_LINKS command execution.

In this way, xgmi ta can reuse the node info in the output buffer
just filled in and populate the same buffer with link info directly.
