BGP: fix shutdown crash when dynamic peer is just connected

Browse Source 
In some edge cases, the dynamic BGP starts but doesn't yet pick up
the socket from the peer, when it gets shut down, typically on
a complete shutdown. Fixing this to just close the socket, not assert
it being already picked up.
