Subject: [PATCH 1/1] 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.
