block: disable sysfs parts of the disk command filter
We still have life time issues with the sysfs command filter kobject, so disable it for 2.6.27 release. We can revisit this and make it work properly for 2.6.28, for 2.6.27 release it's too risky. Signed-off-by: Jens Axboe <jens.axboe@oracle.com>
