Fix CLI path parsing for via interface only

before:
DBGvpp# ip route add 1.1.1.1/32 via mpls-tunnel0
ip route add 1.1.1.1/32 via mpls-tunnel0
ip route: parse error `via mpls-tunnel0'
DBGvpp# ip route add 1.1.1.1/32 via via mpls-tunnel0
ip route add 1.1.1.1/32 via via mpls-tunnel0

after:
DBGvpp# ip route add 1.1.1.1/32 via via mpls-tunnel1
ip route add 1.1.1.1/32 via via mpls-tunnel1
