Charles Yi c8d1e8655c HID: fix HID device resource race between HID core and debugging support 
[ Upstream commit fc43e9c857b7aa55efba9398419b14d9e35dcc7d ]

hid_debug_events_release releases resources bound to the HID device instance.
hid_device_release releases the underlying HID device instance potentially
before hid_debug_events_release has completed releasing debug resources bound
to the same HID device instance.

Reference count to prevent the HID device instance from being torn down
preemptively when HID debugging support is used. When count reaches zero,
release core resources of HID device instance using hiddev_free.

The crash:
