Remove extra prefetch iterator setup for Bitmap Table Scan

Browse Source 
1a0da347a7ac98db replaced Bitmap Table Scan's separate private and
shared bitmap iterators with a unified iterator. It accidentally set up
the prefetch iterator twice for non-parallel bitmap table scans. Remove
the extra set up call to tbm_begin_iterate().
