Melanie Plageman 754c610e13 Fix bitmap table scan crash on iterator release 
1a0da347a7 replaced Bitmap Table Scan's individual private and
shared iterators with a unified iterator. It neglected, however, to
check if the iterator had already been cleaned up before doing so on
rescan. Add this check both on rescan and end scan to be safe.
