[PATCH md ] Fix BUG in raid6 resync code.

This condtion on this loop is primarily to avoid the loop
if it doesn't appear to be needed.  However it optimises
a little too much and there is a case where it skips the
loop when it is really needed.  This patch fixes it.

This is the raid6 version of the recent raid5 resync bugfix.
