sctp_sock_migrate() grabs the socket lock on a newly allocated socket while
holding the socket lock on an old socket. lockdep worries that this might
be a recursive lock attempt.
task/3026 is trying to acquire lock:
(sk_lock-AF_INET){--..}, at: [<ffffffff88105b8c>] sctp_sock_migrate+0x2e3/0x327 [sctp]
but task is already holding lock:
(sk_lock-AF_INET){--..}, at: [<ffffffff8810891f>] sctp_accept+0xdf/0x1e3 [sctp]
This patch tells lockdep that this locking is safe by using
lock_sock_nested().
