Change I4c1b7d33242226b8153821fdc14db54fff764c17 adds
synchronization around country set for connect request so that
if country set is in progress, connect does not proceed as the
channels on which connect is requested can become invalid after
country change.
Add similar change for connection manager as well to avoid above
issue in connection manager path.
