From: Geliang Tang <tanggeliang@xxxxxxxxxx>
The newly added helper create_netns() can be used in assign_reuse.c,
fib_lookup.c, ns_current_pid_tgid.c, sock_destroy.c and sock_iter_batch.c
to simplify the code.
It changes the behavior of test fib_lookup.c a little bit, but doesn't
affect the results.
