[PATCH md 001 of 3] Really get sb_size setting right in all cases.

[NeilBrown <neilb@suse.de>]

There was another case where sb_size wasn't being set, so
instead do the sensible thing and set if when filling in the
content of a superblock.  That ensures that whenever we
write a superblock, the sb_size MUST be set.
