[Qemu-devel] [PATCH 2/5] [S390] Increase amount of virtio pages |

While booting a recent guest, I realized that we're know spawning 2x 64 vrings.
Each vring occupies 3 * PAGE_SIZE size and we only reserved 256 * PAGE_SIZE
bytes where some additional meta info also has to fit in.
This is obviously too little. So let's increase the amount of reserved pages
to a reasonable 1024.
