bpf: Move the "cdg" tcp-cc check to the common sol_tcp_sockopt()
The check on the tcp-cc, "cdg", is done in the bpf_sk_setsockopt which is
used by the bpf_tcp_ca, bpf_lsm, cg_sockopt, and tcp_iter hooks.
However, it is not done for cg sock_ddr, cg sockops, and some of
the bpf_lsm_cgroup hooks.
The tcp-cc "cdg" should have very limited usage. This patch is to
move the "cdg" check to the common sol_tcp_sockopt() so that all
hooks have a consistent behavior. The motivation to make
this check consistent now is because the latter patch will
refactor the bpf_setsockopt(TCP_CONGESTION) into another function,
so it is better to take this chance to refactor this piece
also.
