[PATCH] md: fix typo in super_1_sync

Instead of setting one value lots of times, let's set lots of values once
each, as we should..

This fixes possible inconsistencies that might arise in a version-1 superblock
when devices fail and are removed.

Usage of version-1 superblocks is not yet widespread and no actual problems
have been reported.
