From: Geliang Tang <tanggeliang@kylinos.cn>

The opts.{type, noconnect, must_fail} is at least a bit non intuitive or
unnecessary. The only use case now is in test_bpf_ip_check_defrag_ok which
ends up bypassing most (or at least some) of the connect_to_fd_opts()
logic. It's much better that test should have its own connect_to_fd_opts()
instead.

This patch adds a new "type" parameter for connect_to_fd_opts(), then
opts->type can be replaced by "type" parameter in it.

In test_bpf_ip_check_defrag_ok, different types are passed to it. And the
strcut member "type" of network_helper_opts can be dropped now.
