Subject: [PATCH] input/hog: Remove HID device after HoG device disconnects

When the Bluetooth LE device disconnects, make sure to also destroy the
uHID device so that we don't have a lingering HID device accessible from
user-space.

This also fixes the input subsystem never seeing the device reattaching,
causing settings that should be applied on connection not to be applied.
