Qiushi Wu f4fbb592d9 vfio/mdev: Fix reference count leak in add_mdev_supported_type ...

[ Upstream commit aa8ba13cae ]

kobject_init_and_add() takes reference even when it fails.
If this function returns an error, kobject_put() must be called to
properly clean up the memory associated with the object. Thus,
replace kfree() by kobject_put() to fix this issue. Previous
commit "b8eb718348b8" fixed a similar problem.
