index out of range: go/vnet/ip4.showIpFib

[donnlee]

i8 had a gobgp session established with another gobgp router (pktgen/i14).
i14 sent 4K bgp routes to i8.
Not all routes were installed.
Then i did 'vnet show ip fib' and got a panic:

vnet did not die, but I get the same panic output every time I do 'vnet sh ip fib'.
