Julien Danjou f45cdee4eb event: do not store resize events of banned clients 
This should fix the problem seen with Firefox. When clicking on a
file that will launch a "Save as" dialog, and switching tag quickly,
the client is banned and move off of the viewport.
Then FF send a ConfigureRequest to re-move it to this negative
coordinates, which we did handle and set as its geometries.
Now we just honor the (bad and useless) move but we do not use
client_resize()
