Dan Carpenter ae8ea4e200 vhost-vdpa: fix use after free in vhost_vdpa_probe() ...

[ Upstream commit e07754e0a1ea2d63fb29574253d1fd7405607343 ]

The put_device() calls vhost_vdpa_release_dev() which calls
ida_simple_remove() and frees "v".  So this call to
ida_simple_remove() is a use after free and a double free.
