compat_ioctl: ignore RAID_VERSION ioctl
md ioctls are now handled by the md driver itself, but mdadm may call RAID_VERSION on other devices as well. Mark the command as IGNORE_IOCTL so this fails silently rather than printing an annoying message. Reported-by: "Michael S. Tsirkin" <m.s.tsirkin@gmail.com> Cc: "Rafael J.
