(cherry picked from commit 4540fa0a3e)
In zebra_interface_nhg_reinstall zebra is checking that the
nhg is a singleton and not a blackhole nhg. This was originally
done with checking that the nexthop is a NEXTHOP_TYPE_IFINDEX,
NEXTHOP_TYPE_IPV4_IFINDEX and NEXTHOP_TYPE_IPV6_IFINDEX. This
was excluding NEXTHOP_TYPE_IPV4 and NEXTHOP_TYPE_IPV6. These
were both possible to be received and maintained from the upper
level protocol for when a route is being recursively resolved.
If we have gotten to this point in zebra_interface_nhg_reinstall
the nexthop group has already been installed at least once
and we *know* that it is actually a valid nexthop. What the
test is really trying to do is ensure that we are not reinstalling
a blackhole nexthop group( Which is not possible to even be
here by the way, but safety first! ). So let's change
to test for that instead.

(cherry picked from commit 444ce317b2)
Convert only when this is really needed, e.g. `match ip address prefix-list ...`.
Otherwise, we can't have mixed match clauses, like:
```
match ip address prefix-list p1
match evpn route-type prefix
```
This won't work, because the prefix is already converted, and we can't extract
route type, vni, etc. from the original EVPN prefix.

Currently when one interface changes its VRF, zebra will send these messages to
all daemons in *order*:
1) `ZEBRA_INTERFACE_DELETE` ( notify them delete from old VRF )
2) `ZEBRA_INTERFACE_VRF_UPDATE` ( notify them move from old to new VRF )
3) `ZEBRA_INTERFACE_ADD` ( notify them added into new VRF )
When daemons deal with `VRF_UPDATE`, they use
`zebra_interface_vrf_update_read()->if_lookup_by_name()`
to check the interface exist or not in old VRF. This check will always return
*NULL* because `DELETE` ( deleted from old VRF ) is already done, so can't
find this interface in old VRF.
Send `VRF_UPDATE` is redundant and unuseful. `DELETE` and `ADD` are enough,
they will deal with RB tree, so don't send this `VRF_UPDATE` message when
vrf changes.
Since all daemons have good mechanism to deal with changing vrf, and don't
use this `VRF_UPDATE` mechanism. So, it is safe to completely remove
all the code with `VRF_UPDATE`.

I believe coverity is complaining that the current code does not handle the
realloc fail case, in which case the original pointer is not freed, but NULL is
returned. The code assert()s it's not failed but that is not strong enough it
needs to abort which XREALLOC does and is a better integration into FRR-inrfa
anyway.
