Nguyen Dinh Phi a1ddee82de Bluetooth: hci_sock: purge socket queues in the destruct() callback
commit 709fca500067524381e28a5f481882930eebac88 upstream.

The receive path may take the socket right before hci_sock_release(),
but it may enqueue the packets to the socket queues after the call to
skb_queue_purge(), therefore the socket can be destroyed without clear
its queues completely.

Moving these skb_queue_purge() to the hci_sock_destruct() will fix this
issue, because nothing is referencing the socket at this point.
