Fix race condition that breaks BGP connections after reconfigure.
RFC says that only connections in OpenConfirm and Established state should participate in connection collision detection. The current implementation leads to race condition when both sides are trying to connect at the almost same time, then both sides receive OPEN message by different connections at the almost same time and close the other connection. Both connections are closed and the both sides end in start/idle or start/active state.
