Fix possible "invalid memory alloc request size" failure in nodeHash.c.
Limit the size of the hashtable pointer array to not more than MaxAllocSize. We've seen reports of failures due to this in HEAD/9.5, and it seems possible in older branches as well. The change in NTUP_PER_BUCKET in 9.5 may have made the problem more likely, but surely it didn't introduce it.
