The kernel was recently changed to only connect to ACL devices
sequentially (see kernel commit "Bluetooth: hci_conn: Only do
ACL connections sequentially"), similar to how it already behaves
for LE devices.
Add some testing for this behavior to mgmt-tester and make sure
that new "HCI Create Connection" commands only get sent after
the previous "Pair Device" MGMT command has failed.
