Log Message:
-----------
Fix crash on resolution change -> screen dump -> vga redraw (Avi Kivity)
The vga screen dump function updates last_width and last_height,
but does not change the DisplaySurface that these variables describe.
A consequent vga_draw_graphic() will therefore fail to resize the
surface and crash.
Fix by invalidating the display state after a screen dump, forcing
vga_draw_graphic() to reallocate the DisplaySurface.
