[PATCH] tools/virtio: fix build

[PATCH] tools/virtio: fix build

[Stefano Garzarella]

Fix the build caused by the following changes:
- phys_addr_t is now defined in tools/include/linux/types.h
- dev_warn_once() is used in drivers/virtio/virtio_ring.c
- linux/uio.h included by vringh.h use INT_MAX defined in limits.h
