fdo51023: Revert e4450c54aee85b295b933e91d207fd8220c01107 for Mac OS X

See bug for discussion. Basically, the root cause to the problem is
that on the Mac, all the drag-and-drop action happens during the call
to pSlideSorterViewShell->StartDrag() in the Initialize method. Thus
no wonder that mpDragAndDropContext is null in the ProcessDragEvent()
as it has not been initialized yet, and is in fact initialised
pointlessly only after the drag-and-drop already has finished.

Reverted just for Mac OS X and ifdefified in a straightforward even if
ugly fashion.
