support batching of ip route get commands 

This patch replaces exits with returns in
ip route get command handling. This allows batching
of ip route get commands.

$cat route_get_batch.txt
route get 10.0.14.2
route get 12.0.14.2
route get 10.0.14.4

$ip -batch route_get_batch.txt
local 10.0.14.2 dev lo  src 10.0.14.2
    cache <local>
12.0.14.2 via 192.168.0.2 dev eth0  src 192.168.0.15
    cache
10.0.14.4 dev dummy0  src 10.0.14.2
    cache
