fib: fix crash when create vxlan/vxlan-gpe/geneve/gtpu tunnel.
Fix vpp crash when create vxlan/vxlan-gpe/geneve/gtpu tunnel
with 0.0.0.0 dst ip in debug build. The ASSERT should be move
out of fib_prefix_from_ip46_addr, which may be called when
create vxlan/vxlan-gpe/geneve/gtpu tunnel with 0.0.0.0 dst ip.
How to reproduce:
1. build debug vpp and run vpp
2. create vxlan t src 192.168.0.2 dst 0.0.0.0 vni 1 instance 1
create vxlan-gpe tunnel local 192.168.0.2 remote 0.0.0.0 vni 1
create geneve tunnel local 192.168.0.2 remote 0.0.0.0 vni 1
create gtpu tunnel src 192.168.0.2 dst 0.0.0.0 teid 1
Type: fix
