Bluetooth: Use continuous scanning when initiating LE connections

Browse source 
Since we always do passive scanning and wait for a connectable
advertising event it makes sense to request continous scanning when we
issue the HCI_LE_Create_Connection. This way we minimize the risk of
loosing any advertising packets.
