Bluetooth: Set Scan PHYs based on selected PHYs by user

Browse Source 
Use the PHYs selected in Set Phy Configuration management command
while scanning.

        Own address type: Random (0x01)
        Filter policy: Accept all advertisement (0x00)
        PHYs: 0x05
        Entry 0: LE 1M
          Type: Active (0x01)
