virtio: Add support for guest setting of queue size
...
The MMIO virtio transport spec allows the guest to tell the host how
large the queue size is. Add virtio_queue_set_num() function which
implements this in the QEMU common virtio support code.

virtio: properly validate address before accessing config
...
There are several several issues in the current checking:
- The check was based on the minus of unsigned values which can overflow
- It was done after .{set|get}_config() which can lead crash when config_len
is zero since vdev->config is NULL
Fix this by:
- Validate the address in virtio_pci_config_{read|write}() before
.{set|get}_config
- Use addition instead minus to do the validation
