From: Namhyung Kim <namhyung....@lge.com>
When comparing entries for collapsing put the given entry first, and
then the iterated entry. This is not the case of hist_entry__cmp()
when called if given sort keys don't require collapsing. So change
the order for the sake of consistency. It will be required for
matching and/or linking multiple hist entries.
