When VLAN-VNI mapping is updated, do not set the L2VNI up event if the associated VXLAN device is not up. This may result in bgp synced remote routes to skip installing in Zebra and onwards (Kernel). Ticket: #4139506 Signed-off-by: Chirag Shah <chirag@nvidia.com>

The issue is when bridge flap lead to failure of Type-2/Type-3 route installation.
Upon VxLAN device flap, the associated vlan-vni mapping is processed
before the VxLAN device up netlink notification.
Fix:
When VLAN-VNI mapping is updated, do not set the L2VNI up event
if the associated VXLAN device is not up. This may result in bgp
synced remote routes to skip installing in Zebra and onwards (Kernel).
