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. Wysocki" <rjw@sisk.pl> Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
