drm/amd/display: Set stream_count to 0 when dc_resource_state_destruct.
[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.
