Currently streams are only freed when: - They have no referencing zfetch and and their I/O references go to zero. - They are more than 2s old and a new I/O request comes in on the same zfetch. This means that we will leak unreferenced streams when their zfetch structure is freed. This change checks the reference count on a stream at zfetch free time. If it is zero we free it immediately. If it has remaining references we allow the prefetch callback to free it at I/O completion time.
