*: modify VRF_CONFIGURED flag only in VRF NB layer
This is to fix the crash reproduced by the following steps:
* ip link add red type vrf table 1
Creates VRF.
* vtysh -c "conf" -c "vrf red"
Creates VRF NB node and marks VRF as configured.
* ip route 1.1.1.0/24 2.2.2.2 vrf red
* no ip route 1.1.1.0/24 2.2.2.2 vrf red
(or similar l3vni set/unset in zebra)
Marks VRF as NOT configured.
* ip link del red
VRF is deleted, because it is marked as not configured, but NB node
stays.
Subsequent attempt to configure something in the VRF leads to a crash
because of the stale pointer in NB layer.
Fixes #8357.
