client/x11: fix mode setting in MultyMonScreen::restore

MultyMonScreen::restore changes the X11 Screen resolution, but it
doesn't use MultyMonScreen::set_size. This means
MultyMonScreen::_width and MultyMonScreen::_height don't get
updated to reflect the new resolution settings, which could cause
issues later on. Until now this was safe since the only caller of
MultyMonScreen::restore was MultyMonScreen destructor.
