Bluetooth: mgmt: fix locking in unpair_device/disconnect_sync

Type: advisorySources: OSV

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: mgmt: fix locking in unpair_device/disconnect_sync Dereferencing RCU-protected pointers outside critical sections is invalid and may lead to UAF. Take hdev->lock for hci_conn lookup and hci_abort_conn(). Don't use RCU to ensure the conn is fully initialized at this point.
