zclient: Avoid flapping of nexthop reachability
Currently, GoBGP sends the ROUTE_DELETE messages to Zebra for the paths
whose nexthop was determined as unreachable by IGP, but when Zebra
received the ROUTE_DELETE messages for the unreachable nexthop, Zebra
will send the NEXTHOP_UPDATE message with the given nexthop is
reachable via the default interface. This message unexpectedly causes
updates of the unreachable path to be reachable (not true though). Then
GoBGP will send ROUTE_ADD messages to Zebra, but those paths soon will
be invalidated via the NEXTHOP_UPDATE message, GoBGP will send the
ROUTE_DELETE messages and ... (infinite loop).
This patch fixes to avoid sending the ROUTE_DELETE messages for the
unreachable paths because those paths are inactivated on Zebra and not
installed to FIB.
