numa: add a sysctl for numa_balancing
commit 54a43d54988a3731d644fdeb7a1d6f46b4ac64c7 upstream.
Add a working sysctl to enable/disable automatic numa memory balancing
at runtime.
This allows us to track down performance problems with this feature and
is generally a good idea.
This was possible earlier through debugfs, but only with special
debugging options set. Also fix the boot message.
