I think you should leave it as is, the "device_set" cleanup is just
something handled completely internally to vfio

If ops->init fails then we expect the core code to clean the
device_set, and it does because it calls vfio_init_device() already.

Having a single weirdly placed release in the driver is pretty
confusing, IMHO.
