bgpd: improve bgp convergence, with bfd up
Bgp periodically tries to reconnect, while the connection
is down. When bfd event comes up, BGP is not aware that bfd connection
is up, then BGP can not adapt its reconnection timer. The modification
is here to force BGP to restart, when BFD event comes up, and BGP has
not yet established.
