mptcp: refine opt_mp_capable determination
[ Upstream commit 724b00c12957973656d312dce2a110c75ae2c680 ]
OPTIONS_MPTCP_MPC is a combination of three flags.
It would be better to be strict about testing what
flag is expected, at least for code readability.
mptcp_parse_option() already makes the distinction.
- subflow_check_req() should use OPTION_MPTCP_MPC_SYN.
- mptcp_subflow_init_cookie_req() should use OPTION_MPTCP_MPC_ACK.
- subflow_finish_connect() should use OPTION_MPTCP_MPC_SYNACK
- subflow_syn_recv_sock should use OPTION_MPTCP_MPC_ACK
