HidHost: Do not reject first outgoing connection attempt

Connection is rejected if the connection state and connection policy
indicate that connection was not expected. For the first time
connections, connection policy and connection state are not available.
In such cases, pending connection link spec should be compared to find
if the connection was intentional or not.
