[PATCH] Bluetooth: AMP contollers do not support the legacy ioctls

[Marcel Holtmann <marcel@holtmann.org>]

The legacy ioctls for device specific commands including inquiry are
not support by AMP controllers. So just reject them right away instead
of trying to send the HCI command and wait for failure from the
actual hardware.
