Brian Foley 3850d29fc4 virtio_mmio: fix off by one error allocating queue ... vm_setup_vq fails to allow VirtQueues needing only 2 pages of storage, as it should. Found with a kernel using 64kB pages, but can be provoked if a virtio device reports QueueNumMax where the descriptor table and available ring fit in one page, and the used ring on the second (<= 227 descriptors with 4kB pages and <= 3640 with 64kB pages.)
