[virt-tools-list] [PATCH virt-viewer 1/2] virt_viewer_window_resize: Remove dead code

[Hans de Goede]

The if () { if () x; else y; } else z; block this commit removes, is a nop:

The z block does:
 width = desktopWidth;
 height = desktopHeight;

The x block does:
 width = desktopHeight * desktopAspect;
 height = desktopHeight;
Where the width = ... can also be written as:
 width = desktopHeight * desktopWidth / desktopHeight;
Which can be simplified to:
 width = desktopWidth;

Like wise the height setting in the y block can be simplified to:
height = desktopHeight; too.

So all 3 branches do the same, and the entire block of code can be removed.
