Register debugfs entries before calling device_add() so debugfs entries are
already present when HID driver's probe function gets called on device hotplug.
Also undo debugfs entry registration if device_add() fails so status
HID_STAT_ADDED and debugfs registration status remain consistent and we don't
leak the debugfs entries.
