vfio/mdev: Pass in a struct vfio_device * to vfio_pin/unpin_pages()
Every caller has a readily available vfio_device pointer, use that instead
of passing in a generic struct device. The struct vfio_device already
contains the group we need so this avoids complexity, extra refcountings,
and a confusing lifecycle model.
