daemon_vty: avoid null-dereference in argc < 0 case

in show_gtp_cmd, we have two different checks (argc > 0) vs (argc)
which means in theory argc could be negative and the second clause
would be executed without the first having set up related data such as
'ai'.

Fixes: CID#307521: Explicit null dereferenced (FORWARD_NULL)
