From: Paul Wu <paul.wu@xxxxxxx> [Why] When hardware need to be reset, driver need to reset stream objects but dc_resource_state_destruct function omit resetting stream_count. It will lead page fault if some logic will touch stream object. [How] Set stream_count to 0 when dc_resource_state_destruct.
