um: virtio: free vu_dev only with the contained struct device
[ Upstream commit f4172b08 ] Since struct device is refcounted, we shouldn't free the vu_dev immediately when it's removed from the platform device, but only when the references actually all go away. Move the freeing to the release to accomplish that.
