Revert of Simplify the logic in DesktopWindowTreeHostX11 for FocusOut (https://codereview.chromium.org/379773003/)

Reason for revert:
I am reverting this CL because it causes regressions like crbug.com/395985. This CL is in the right direction, but I need to make the capture code for tab dragging less crazy first. See comment #3 in crbug.com/395985 for more details

Original issue's description:
> Simplify the logic in DesktopWindowTreeHostX11 for FocusOut
> 
> We should have the same handling regardless of whether the 'mode' member is
> NotifyGrab or NotifyUngrab. According to
> http://tronche.com/gui/x/xlib/events/input-focus/grab.html, whether the mode
> field is NotifyGrab or NotifyUngrab depends on whether there is a new
> capturer for the keyboard. The X window has lost keyboard capture in both cases.
