[bpf-next,5/5] selftests/bpf: Drop useless arguments of do_test in bpf_tcp_ca

Commit Message

From: Geliang Tang <[e-mail]>

bpf_map_lookup_elem() has been removed from do_test(), it makes the
sk_stg_map argument of do_test() useless. In addition, two exactly the
same opts are passed in all the places where do_test() is invoked, so
cli_opts argument can be dropped too.

This patch drops these two useless arguments of do_test() in bpf_tcp_ca.c.
