linux-cp: Fix looping netlink messages
Signal when consuming a batch of netlink messages, in order to inhibit
lcp_sync from generating new netlink messages. This avoids link up/down
state changess from triggering an infinite loop.
Do this in the regular case of nl_route_process_msgs()
and in the special case of re-synchronizing in lcp_nl_recv_dump_replies().
Type: fix
