Commit 653055b9acd4 ("vhost-vdpa: support get/set backend features")
introduces two malfunction backend features ioctls:
1) the ioctls was blindly added to vring ioctl instead of vdpa device
ioctl
2) vhost_set_backend_features() was called when dev mutex has already
been held which will lead a deadlock
This patch fixes the above issues.

Don't we want the fixes queued right now, as opposed to the rest of the
RFC?
Yes, actually I've posted in before[1].
Adding the patch here is to simplify the work for the guys that want to
do the work on top. E.g for Cindy to start the Qemu prototype.
Thanks
