Fixes a crash when CompleteDrag is called twice with two-finger drag. Second call to FinishDragging would always crash. I suspect that resizer->CompleteDrag is called twice when first and then second fingers are lifted.

BUG=305730
TEST=Touch-drag a window with one, then two fingers under --enable-docked-windows flag.
