thunderbolt: Do not report errors if on-board retimers are found

Browse Source 
commit c28f3d8038 upstream.

Currently we return an error even if on-board retimers are found and
that's not expected. Fix this to return an error only if there was one
and 0 otherwise.

Fixes: 1e56c88ade ("thunderbolt: Runtime resume USB4 port when retimers are scanned")
