md: Handle growth of v1.x metadata correctly.
commit 70471dafe3390243c598a3165dfb86b8b8b3f4fe upstream.
The v1.x metadata does not have a fixed size and can grow
when devices are added.
If it grows enough to require an extra sector of storage,
we need to update the 'sb_size' to match.
Without this, md can write out an incomplete superblock with a
bad checksum, which will be rejected when trying to re-assemble
the array.
