Bluetooth: Fix HCI init for BlueFRITZ! devices
None of the BlueFRITZ! devices with manufacurer ID 31 (AVM Berlin) support HCI_Read_Local_Supported_Commands. It is safe to use the manufacturer ID (instead of e.g. a USB ID specific quirk) because the company never created any newer controllers. < HCI Command: Read Local Supported Comm..
