vfio/mdev: Make to_mdev_device() into a static inline
The macro wrongly uses 'dev' as both the macro argument and the member name, which means it fails compilation if any caller uses a word other than 'dev' as the single argument. Fix this defect by making it into proper static inline, which is more clear and typesafe anyhow.
