Let's say FRR is compiled with ECMP max 16, we enter `allow-ecmp 10`, but
Zebra supports only 4.

There are two issues being addressed:
a) The ZEBRA_ON_RIB_PROCESS_HOOK_CALL script point
was creating a fs pointer per dplane ctx in
rib_process_dplane_results().
b) The fs pointer was not being deleted and directly
leaked.
For (a) Move the creation of the fs to outside
the do while loop.
For (b) At function end ensure that the pointer
is actually deleted.

1. No any configuration in FRR, and `ip link add vrf1 type vrf ...`.
Currently, everything is ok.
2. `ip link del vrf1`.
`zebra` will wrongly/redundantly notify clients to add "vrf1" as a normal
interface after correct deletion of "vrf1".

```
`if_handle_vrf_change()` moved the interface from specific vrf to default
vrf. But it doesn't skip interface of vrf type. So, the wrong/redundant
add operation is done.
Note, the wrong add operation is regarded as an normal interface because
the `ifp->status` is cleared too early, so it is without VRF flag
( `ZEBRA_INTERFACE_VRF_LOOPBACK` ). Now, ospfd will initialize `ifp->type`
to `OSPF_IFTYPE_BROADCAST`.
3. `ip link add vrf1 type vrf ...`, add "vrf1" again. FRR will be with
wrong display:
```
interface vrf1
ip ospf network broadcast
exit
```
Here, zebra will send `ZEBRA_INTERFACE_ADD` again for "vrf1" with
correct `ifp->status`, so it will be updated into vrf type. But
it can't update `ifp->type` from `OSPF_IFTYPE_BROADCAST` to
`OSPF_IFTYPE_LOOPBACK` because it had been already configured in above
step 2.
Two changes to fix it:
1. Skip the procedure of switching VRF for interfaces of vrf type.
It means, don't send `ZEBRA_INTERFACE_ADD` to clients when deleting vrf.
2. Put the deletion of this flag at the last.
It means, clients should get correct `ifp->status`.
