Maxime Coquelin e1e4fb853a vduse: Temporarily fail if control queue feature requested
[ Upstream commit 56e71885b0 ]

Virtio-net driver control queue implementation is not safe
when used with VDUSE. If the VDUSE application does not
reply to control queue messages, it currently ends up
hanging the kernel thread sending this command.

Some work is on-going to make the control queue
implementation robust with VDUSE. Until it is completed,
let's fail features check if control-queue feature is
requested.
