mptcp: factor out __mptcp_close() without socket lock
Factor out __mptcp_close() from mptcp_close(). The caller of
__mptcp_close() should hold the socket lock, and cancel mptcp work when
__mptcp_close() returns true.
This function will be used in the next commit.
Fixes: f296234c98a8 ("mptcp: Add handling of incoming MP_JOIN requests")
Fixes: 6aeed9045071 ("mptcp: fix race on unaccepted mptcp sockets")
