Bluetooth: af_bluetooth: Fix deadlock

In the Linux kernel, the following vulnerability has been resolved:

Bluetooth: af_bluetooth: Fix deadlock

Attemting to do sock_lock on .recvmsg may cause a deadlock as shown

bellow, so instead of using sock_sock this uses sk_receive_queue.lock

on bt_sock_ioctl to avoid the UAF:

INFO: task kworker/u9:1:121 blocked for more than 30 seconds.

Not tainted 6.7.6-lemon #183
