Lin Ma 74caf718cc Bluetooth: use correct lock to prevent UAF of hdev object 
commit e305509e678b3a4af2b3cfd410f409f7cdaabb52 upstream.

The hci_sock_dev_event() function will cleanup the hdev object for
sockets even if this object may still be in used within the
hci_sock_bound_ioctl() function, result in UAF vulnerability.

This patch replace the BH context lock to serialize these affairs
and prevent the race condition.
