Marcel Holtmann 45bb4bf08b [Bluetooth]: Workaround for inquiry results with RSSI and page scan mode 
This patch implements a workaround for buggy Bluetooth 1.2 devices from
Silicon Wave. Their inquiry results with RSSI contain the page scan mode
field. This field was removed in the final Bluetooth 1.2 specification.
