Limit Parallel Hash's bucket array to MaxAllocSize. Make sure that we don't exceed MaxAllocSize when increasing the number of buckets. Perhaps later we'll remove that limit and use DSA_ALLOC_HUGE, but for now just prevent further increases like the non-parallel code. This change avoids the error from bug report #15225.
