    Description

      CellUtil.createFirstOnRow is more effective than KeyValueUtil.createFirstOnRow, because there is no byte[] copy.

      Current in ReversedRegionScannerImpl#nextRow, to get the previous row to seek, it use KeyValueUtil.createFirstOnRow which will have two copy, the first copy is copy to a tmp byte[], the second copy is in KeyValue. We can use CellUtil.createFirstOnRow which will have no copy.
