md: raid10: add prerequisite to run underneath dm-raid
In case md runs underneath the dm-raid target, the mddev does not have a request queue or gendisk, thus avoid accesses to it. This patch adds two missing conditionals to the raid10 personality. Signed-of-by: Heinz Mauelshagen <heinzm@redhat.com> Signed-off-by: Shaohua Li <shli@fb.com>
