ipmr: Use on-device stats instead of private ones.
These devices use the private area of appropriate size for statistics. Turning them to use on-device ones make them "privless" and thus - really small wrt kmalloc cache, they are allocated from. Besides, code looks nicer, because of absence of multi-braced type casts and dereferences. [ Fix build failures -DaveM ] Signed-off-by: Pavel Emelyanov <xemul@openvz.org> Signed-off-by: David S.
