bgpd: fix issue with ipv6 ecmp with vrfs
Problem reported by customer that ipv6 wasn't installing ecmp paths
when using vrfs. Found a vrf-unware call in bgp_zebra_announce that
was the culprit. Testing of the fix looks good.

zebra: stop deregistering static nexthops unless removing the static
Problem reported was that with some overlapping static route configurations,
when the link went down the less specific static was not re-installed after
the link came back up. Determined that with the overlapping statics, we
would recursively resolve the next-hop temporarily thru the more specific
static route, but since the next-hop wasn't actually reachable, we would go
through the code that clears the nht information for the static completely.
This caused the nht code to no longer process the static route.
After reviewing the process, there doesn't seem to be any reason that the
static should be deregistered in that section of code. Removed the
deregister and the problem is resolved and not addional failures seen in
manual testing. zebra_test.py completed successfully and ospf and bgp smokes
completed with no new failures.

zebra: Move interfaces to default before deleting
Encountered a crash in zebra due to getting a delete on an SVI with
VRR configured. Since we don't actually do a delete but flag the interface
as inactive, slag VRR interfaces would remain on the vrf_iflist with a lock
count of zero, causing the crash. Since all other interface types are moved
to the default table before deleting, doing the same thing for any interfaces
that were left in the vrf.
Testing includes manual testing, bgp-min, ospf-min, vrf-min, bgp-smoke, and ospf-smoke.
All passed (first time or on rerun) or match known failures.

bgpd: resolve ipv6 ecmp issue with vrfs and ll nexthop
Problem reported that ecmp wasn't working correctly in a vrf with

with a link-local nexthop and nhlen of 16. In this particular case,
bgp_zebra_announce was using the wrong call to get the ifindex and
was not supplying the vrf. This caused ecmp to work only in the case
of the default vrf.

- This's the wrong way to fix this problem.
- Since the "TAILQ_FIRST()" always return diferent pointer as we call "TAILQ_REMOVE()", the clang static analyzer can't detect this behavior.
- Ignore this warning and keep files identical to its original one.
