wm: Fix drag to maximize for touches on bezel.

I forget why i put the extra check in the first place, I think did it
in case the displays are stacked vertically and dragging i thought maybe
dragging from the bottom to top display would trigger a maximize. But
we pass the display as well, so that is not a problem. Removing the
extra check allows for touch dragging on bezel.
