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:
