virtio: Fix wrong type cast from pointer to long
Compiler warning (w32, w64): include/hw/virtio/virtio_ring.h:142:26: warning: cast from pointer to integer of different size [-Wpointer-to-int-cast] When sizeof(long) < sizeof(void *), this is not only a warning but a real program error. Add also missing blanks in the same statement.
