qxl: call dpy_gfx_resize when entering vga mode 

When entering vga mode the display size likely changes,
notify all displaychangelisteners about this.

Probably went unnoticed for a while as one if the first
things the guest does after leaving qxl native mode and
entering qxl vga mode is to set the vga video mode.  But
there is still a small window where qemu can operate on
stale data, leading to crashes now and then.
