Bluetooth: Disconnect HIDRAW devices on disconnect

commit 364f63519d94442ed373ac7da79033c8282df46a upstream.

Currently the HID subsystem will create HIDRAW devices for the transport
driver, but it will not disconnect them. Until the HID subsytem gets
fixed, ensure that HIDRAW and HIDDEV devices are disconnected when the
Bluetooth HID device gets removed.

Based on a patch from Brian Rogers <brian@xyzw.org>
