MD: set journal disk ->raid_disk
Set journal disk ->raid_disk to >=0, I choose raid_disks + 1 instead of 0, because we already have a disk with ->raid_disk 0 and this causes sysfs entry creation conflict. A lot of places assumes disk with ->raid_disk >=0 is normal raid disk, so we add check for journal disk. Signed-off-by: Shaohua Li <shli@fb.com> Signed-off-by: NeilBrown <neilb@suse.com>
