Amit Kapila 75f9c4ca5a Don't allow LIMIT/OFFSET clause within sub-selects to be pushed to workers. 
Allowing sub-select containing LIMIT/OFFSET in workers can lead to
inconsistent results at the top-level as there is no guarantee that the
row order will be fully deterministic.  The fix is to prohibit pushing
LIMIT/OFFSET within sub-selects to workers.
