Bluetooth: Use continuous scanning when creating LE connections
commit 2f99536a5b34d5b0f54723067d68f6cef3f0fdc6 upstream.
All LE connections are now triggered through a preceding passive scan
and waiting for a connectable advertising report. This means we've got
the best possible guarantee that the device is within range and should
be able to request the controller to perform continuous scanning. This
way we minimize the risk that we miss out on any advertising packets.
