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.
