From: Geliang Tang tanggeliang@kylinos.cn
The struct member "must_fail" of network_helper_opts() is only used in cgroup_v1v2 tests, it makes sense to drop it from network_helper_opts.
Return value (fd) of connect_to_fd_opts() and the expect errno (EPERM) can be checked in cgroup_v1v2.c directly, no need to check them in connect_fd_to_addr() in network_helpers.c.
This also makes connect_fd_to_addr() function useless. It can be replaced by connect().
