From: Geliang Tang <tanggeliang@kylinos.cn>

This patch uses cleanup_netns() helper in BPF tests wide to replace
close_netns() and "ip netns del", included assign_reuse.c, crypto_sanity.c,
decap_sanity.c, fib_lookup.c, ns_current_pid_tgid.c, sock_destroy.c,
sock_iter_batch.c, xdp_dev_bound_only.c and xdp_do_redirect.c. This can
simplify the code.
