The commit 15c8e72e88e0 ("fuse: allow skipping control
interface and forced unmount") tries to remove the control
interface for virtio-fs since it does not support aborting
requests which are being processed. But it doesn't work now.
This patch fixes it by skipping creating the control interface
if fuse_conn->no_control is set.
