[Qemu-devel] [PULL v3 18/21] vhost-user: delete chardev on cleanup

["Michael S. Tsirkin" <mst@redhat.com>]

From: Marc-André Lureau <marcandre.lureau@redhat.com>

Remove the chardev implicitly when cleaning up the netdev. This
prevents from reusing the chardev since it would be in an incorrect
state with the slave.
