When stub stream is closed early, then queries associated to the stream are freed. Previously, the timer event source for queries may not be disabled, hence may be triggered with already freed query. See also dns_stub_stream_complete(). Note that we usually not set NULL or zero when freeing simple objects. But, here DnsQuery is large and complicated object, and the element may be referenced in subsequent freeing process in the future. Hence, for safety, let's set NULL to the pointer.
