Make stream_destroy() use weston_log_subscriber_release(). This avoids code duplication and allow us to destroy weston_log_subscriber_get_only_subscription(), since it's being used only in this case and it's internal. Calls for weson_log_subscriber_release() leads to weston_log_debug_wayland_to_destroy(), which should not send an error event when the stream has already been closed. Also, stream_destroy() shouldn't lead to an event error, as it is a wl_resource destroy handler. So close the stream before calling weston_log_subscriber_release() in stream_destroy() Signed-off-by: Leandro Ribeiro <leandrohr@riseup.net>
