Detail: handle non-existent arrays better.
If you call "mdadm --detail" with a device file for an array which
doesn't exist, such as by
mknod /dev/md57 b 9 57
mdadm --detail /dev/md57
you get an unhelpful message about and inactive RAID0, and return
status is '0'. This is confusing.
So catch this possibility and print a more useful message, and
return a non-zero status.
