Subject: [PATCH] net/virtio: fix memory leak of interrupt handle

Free memory of interrupt handle in virtio_user_dev_uninit() to
avoid memory leak.
when virtio user dev closes, memory of interrupt handle is not freed
that is allocated in virtio_user_fill_intr_handle().

Fixes: 3d4fb6fd2505 <"net/virtio-user: support Rx interrupt">
