[virt-tools-list] [virt-viewer 1/3] display: Only queue a resize on zoom-level changes

[Fabiano Fidêncio]

By the comment in the code:
"For the gtk2 build, we need to queue a resize even if the zoom level
 hasn't changed.  This is due to the fact that VirtViewerWindow will
 queue a resize event for itself immediately after calling this
 function (in  order to shrink the window to fit the new display size
 if necessary). If we don't queue a resize here, the window will become
 tiny because we will only request 50x50 during the window resize."

And it doesn't happen on gtk3 at all. So, let's just remove the comment
and just quere the resize when zoom-changes actually happen.
