bgpd: Restarting node does not send EOR after the convergence.
*After a restarting router comes up and the bgp session is
successfully established with the peer. If the restarting
router doesn’t have any route to send, it send EOR to
the peer immediately before receiving updates from its peers.
*Instead the restarting router should send EOR, if the
selection deferral timer is not running OR count of eor received
and eor required are matches then send EOR.
