drm: clean dirty memory after device release
In current code we register/unregister connector object by
drm_sysfs_connector_add/remove function.
However under some cases, we need to dynamically register or unregister device
multiple times, so we have to go through register -> unregister ->register
routine.
Because after device_unregister function our memory is dirty, we need to do
clean operation in order to re-register the device, otherwise the system
will crash. The patch intends to clean device after device release.
