[PATCH] md: fix for raid6 reshape
Recent patch for raid6 reshape had a change missing that showed up in
subsequent review.
Many places in the raid5 code used "conf->raid_disks-1" to mean "number of
data disks". With raid6 that had to be changed to "conf->raid_disk -
conf->max_degraded" or similar. One place was missed.
This bug means that if a raid6 reshape were aborted in the middle the
recorded position would be wrong. On restart it would either fail (as the
position wasn't on an appropriate boundary) or would leave a section of the
array unreshaped, causing data corruption.
