Revert "Merge pull request #1732 from VoltDB/ENG-7018-limit-rows-execute-ee"


This reverts commit 7c7f8723538e5c891bd2fbcbd6179d0be7c1e0ee, reversing
changes made to 0ca73a8cc1d7ec5b6c0eae8483a9464137f63577.

This seems to have caused a performance regression.  Phil has confirmed that this revert addresses it.

(Still murky as to why this would cause the slowdown)
Maybe all these extra boolean checks slow down the EE, but should not be so much. Still weird.
