When a nexthop group is modified do not assume that it

it is not needed to set it as not installed.

zebra: resolve assert when adding ip import-table entry
Problem was due to in certain route replace circumstances,
we would mark the old route_entry as removed to delete it but
would leave the selected flag set. When the rn was pulled off the
work queue for process, we would find both the new re and old re
(being deleted) with the selected flag set and would assert.
In this change, when we decide to delete the old re, we also mark
it as no longer selected.

The pbr_rule structure is derived from zebra_pbr_rule, and is

zebra: add EVPN learned neighbors as NUD_NOARP
EVPN owns the remote neigh entries which are programed in the kernel.
This entries should not age out and the only way to delete should be
from EVPN. We should program these entries with NUD_NOARP instead of
NUD_REACHABLE to avoid aging of this macs.
zebra: act on kernel notifications for remote neighbors as well
There can be a race condition between kernel and frr as follows.
Frr sends remote neigh notification.
At the (almost) same time kernel might send a notification saying
neigh is local.
After processing this notifications, the state in frr is local while
state in kernel is remote. This causes kernel and frr to be out of sync.
This problem will be avoided if FRR acts on the kernel notifications for
remote neighbors. When FRR sees a remote neighbor notification for a
neighbor which it thinks is local, FRR will change the neigh state to remote.
