virtio_pci: fix use after free on release
commit 2989be09a8a9d62a785137586ad941f916e08f83 upstream.
KASan detected a use-after-free error in virtio-pci remove code. In
virtio_pci_remove(), vp_dev is still used after being freed in
unregister_virtio_device() (in virtio_pci_release_dev() more
precisely).
To fix, keep a reference until cleanup is done.
Fixes: 63bd62a08ca4 ("virtio_pci: defer kfree until release callback")
