* This function is called to set a Fast Open socket's "fastopen_rsk" field
* to NULL when a TFO socket no longer needs to access the request_sock.
* This happens only after 3WHS has been either completed or aborted (e.g.,
* RST is received).
*
* Before TFO, a child socket is created only after 3WHS is completed,
* hence it never needs to access the request_sock. things get a lot more
* complex with TFO. A child socket, accepted or not, has to access its
* request_sock for 3WHS processing, e.g., to retransmit SYN-ACK pkts,
* until 3WHS is either completed or aborted. Afterwards the req will stay
* until either the child socket is accepted, or in the rare case when the
* listener is closed before the child is accepted.
*
* In short, a request socket is only freed after BOTH 3WHS has completed
* (or aborted) and the child socket has been accepted (or listener closed).
* When a child socket is accepted, its corresponding req->sk is set to
* NULL since it's no longer needed. More importantly, "req->sk == NULL"
* will be used by the code below to determine if a child socket has been
* accepted or not, and the check is protected by the fastopenq->lock
* described below.
*
* Note that fastopen_rsk is only accessed from the child socket's context
* with its socket lock held. But a request_sock (req) can be accessed by
* both its child socket through fastopen_rsk, and a listener socket through
* icsk_accept_queue.rskq_accept_head. To protect the access a simple spin
* lock per listener "icsk->icsk_accept_queue.fastopenq->lock" is created.
* only in the rare case when both the listener and the child locks are held,
* e.g., in inet_csk_listen_stop() do we not need to acquire the lock.
* The lock also protects other fields such as fastopenq->qlen, which is
* decremented by this function when fastopen_rsk is no longer needed.
*
* Note that another solution was to simply use the existing socket lock
* from the listener. But first socket lock is difficult to use. It is not
* a simple spin lock - one must consider sock_owned_by_user() and arrange
* to use sk_add_backlog() stuff. But what really makes it infeasible is the
* locking hierarchy violation. E.g., inet_csk_listen_stop() may try to
* acquire a child's lock while holding listener's socket lock. A corner
* case might also exist in tcp_v4_hnd_req() that will trigger this locking
* order.
*
* When a TFO req is created, it needs to sock_hold its listener to prevent
* the latter data structure from going away.
*
* This function also sets "treq->listener" to NULL and unreference listener
* socket. treq->listener is used by the listener so it is protected by the
* fastopenq->lock in this function.
