Bluetooth: Remove BlueFritz! specific check from initialization

The AVM BlueFritz! USB controllers had a special handling in the
Bluetooth core when it comes to reading the supported commands.

Both drivers now set the HCI_QUIRK_BROKEN_LOCAL_COMMANDS and with
that it is no longer needed to look for vendor specific details.
