[PATCH 1/2] comctl32: Listview - prevent DragDetect from removing WM_LBUTTONUP messages.

Hi,

I noticed bug 14908 wasn't quite fixed on some systems. Due to minute
mouse movements, sometimes we get unintended mouse movements while the
mouse button is down. When this happens, DragDetect() in
LISTVIEW_MouseMove() eats up the WM_LBUTTONUP messages. To remedy
this, we peek at the messages, and skip the DragDetect() if we see a
WM_LBUTTONUP.
