virtio: fix vring_align() on 64-bit windows
long is 32-bits on 64-bit windows, which caused the top half of the address to be truncated; this patch changes it to use the QEMU_ALIGN_UP macro which does not suffer the same problem Signed-off-by: Andrew Baumann <Andrew.Baumann@microsoft.com> Reviewed-by: Eric Blake <eblake@redhat.com> Reviewed-by: Michael S.
