Revert "net/sctp: fix race condition in sctp_destroy_sock"
commit 01bfe5e8e428b475982a98a46cca5755726f3f7f upstream.
This reverts commit b166a20b07382b8bc1dcee2a448715c9c2c81b5b.
This one has to be reverted as it introduced a dead lock, as
syzbot reported:
CPU0 CPU1
---- ----
lock(&net->sctp.addr_wq_lock);
lock(slock-AF_INET6);
lock(&net->sctp.addr_wq_lock);
lock(slock-AF_INET6);
CPU0 is the thread of sctp_addr_wq_timeout_handler(), and CPU1
is that of sctp_close().
The original issue this commit fixed will be fixed in the next
patch.
