UBIFS: reserve more space for index
At the moment UBIFS reserves twice old index size space for the index. But this is not enough in some cases, because if the indexing node are very fragmented and there are many small gaps, while the dirty index has big znodes - in-the-gaps method would fail. Thus, reserve trise as more, in which case we are guaranteed that we can commit in any case. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
