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.
