md/raid10: Fix bug when activating a hot-spare.
commit 7fcc7c8acf0fba44d19a713207af7e58267c1179 upstream.
This is a fairly serious bug in RAID10.
When a RAID10 array is degraded and a hot-spare is activated, the
spare does not take up the empty slot, but rather replaces the first
working device.
This is likely to make the array non-functional. It would normally
be possible to recover the data, but that would need care and is not
guaranteed.
This bug was introduced in commit
2bb77736ae5dca0a189829fbb7379d43364a9dac
which first appeared in 3.1.
