md: don't impose the MD_SB_DISKS limit on arrays without metadata.
These arrays, created with "mdadm --build" don't benefit from a limit. The default will be used, which is '0' and is interpreted as "don't impose a limit". Reported-by: ian_bruce@mail.ru Signed-off-by: NeilBrown <neilb@suse.com> Signed-off-by: Shaohua Li <shli@fb.com>
