vga_common_init() doesn't allow more than 256 MiB vram size and silently
shrinks any larger value. qxl_dirty_surfaces() used the unshrinked size
via qxl->shadow_rom.surface0_area_size when accessing the memory, which
resulted in segfault.
Add a workaround for this case and an assert if it happens again.
We have to bump the vga memory limit too, because 256 MiB wouldn't have
allowed 8k (it requires more than 128 MiB).
1024 MiB doesn't work, but 512 MiB seems fine.
