perf hists: Exchange order of comparing items when collapsing hists

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.
