re-fix screendump (Stefano Stabellini) 



Removing the assumption about a single graphic console made
get_graphic_console return NULL when called by vga_screen_dump.
In this case returning NULL is correct but since NULL is not handled in
qemu_console_resize it causes a segmentation fault.
Just returning immediately from qemu_console_resize is sufficient to fix the
problem.
