Patch 1 removes an unneeded address copy in subflow_syn_recv_sock().
Patch 2 simplifies subflow_syn_recv_sock() to postpone some actions and to avoid a bunch of conditionals.
Patch 3 stops reporting limits that are not taken into account when the userspace PM is used.
Patch 4 adds a new test to validate that the 'subflows' field reported by the kernel is correct. Such info can be retrieved via Netlink (e.g. with ss) or getsockopt(SOL_MPTCP, MPTCP_INFO).
