vhost-vdpa: fix backend feature ioctls
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.
