The call to gm_update_ll checks for null pointers and

This is not true with the code flow. Remove the confusing code.

Zebra can be setup to use a value that is less than MULTIPATH_NUM.
When pimd connects to zebra, zebra will inform pim about the MULTIPATH_NUM
used. Let's use that value for figuring out our multipath value.

Coverity SA thinks that the `struct prefix`.u.prefix4 is limited
to actually 4 bytes of memory at that spot, but it's in a union
and it can be treated as a prefix6 as well. Just change the
pointer assignment to something that covers both easily.

Currently kernel routes on system bring up would be `auto-accepted`,
then if an interface went down all kernel and system routes would
be re-evaluated. There exists situations where a kernel route can
exist but the interface itself is not exactly in a state that is
ready to create a connected route yet. As such when any interface
goes down in the system all kernel/system routes would be re-evaluated
and then since that interfaces connected route is not in the table yet
the route is matching against a default route( or not at all ) and
is being dropped.
Modify the code such that kernel or system routes just look for interface
being in a good state (up or operative) and accept it.

The two checks for l3vni have been already done in
`lib_vrf_zebra_l3vni_id_modify()` as it should be. And it is improper that
the two checks are put after `zebra_vxlan_handle_vni_transition()`, which
will do real things.
My original fix is to remove them. But NB module can't guarantee many changes,
so we'd better keep them in `zebra_vxlan_process_vrf_vni_cmd()` in APPLY stage
for safe.
Just move them in front of `zebra_vxlan_handle_vni_transition()`.
