Bluetooth: hci_conn: Fix UAF Write in __hci_acl_create_connection_sync
[ Upstream commit 5f641f03abccddd1a37233ff1b8e774b9ff1f4e8 ]
This fixes the UAF on __hci_acl_create_connection_sync caused by
connection abortion, it uses the same logic as to LE_LINK which uses
hci_cmd_sync_cancel to prevent the callback to run if the connection is
abort prematurely.
