mptcp: sockopt: make 'tcp_fastopen_connect' generic
There are other socket options that need to act only on the first subflow, e.g. all TCP_FASTOPEN* socket options. This is similar to the getsockopt version. In the next commit, this new mptcp_setsockopt_first_sf_only() helper is used by other another option.
