Geliang Tang 83ca1efe50 selftests/bpf: Fix umount cgroup2 error in test_sockmap
[ Upstream commit d75142dbeb2bd1587b9cc19f841578f541275a64 ]

This patch fixes the following "umount cgroup2" error in test_sockmap.c:

 (cgroup_helpers.c:353: errno: Device or resource busy) umount cgroup2

Cgroup fd cg_fd should be closed before cleanup_cgroup_environment().

Fixes: 13a5f3ffd202 ("bpf: Selftests, sockmap test prog run without setting cgroup")
