fuse: Remove the control interface for virtio-fs
[ Upstream commit c64797809a64c73497082aa05e401a062ec1af34 ]
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.
