[llvm-exegesis] Fix validation counters

While landing llvm#76652, I realized I messed up a rebase/merge at some
point and some of the changes I intended to land with llvm#76652 ended up in
a different PR (llvm#76653) instead. This patch fixes the validation
counters to how they were intended to land in llvm#76652.
