As mentioned in commit there is qualification test which tests it.

GAP/DISC/GENM/BV-03-C
[General Discoverable Mode Non-Connectable Mode - LE Only]

That said, this patch isn't valid since in bluetoothd discoverable requires 
connectable so currently we are not able to configure non-connectable 
advertising instance when discoverable.

I think we should extend Add Advertising mgmt command with flag that would 
allow to force non-connectable advertising regardless of global connectable 
flag.

Thoughts?
