virtio_config: fix len calculation of config elements
Rusty,
This patch is a prereq for the virtio_blk blocksize patch, please apply it
first.
Adding an u32 value to the virtio_blk_config unconvered a small bug the config
space defintions:
v is a pointer, to we have to use sizeof(*v) instead of sizeof(v).
