shell32: Revert c1f2824429286dd60fac723611b801e67eb745b1. It caused poor performance.

Patch c1f2824429286dd60fac723611b801e67eb745b1 causes poor performance
when browsing a directory. In fact it has a side affect that when you
browse the root folder off of My Computer it will enumerate not only
the root's contents but each subfolder's contents as well in order to
get a more likely correct value for SFGAO_HASSUBFOLDER.
