[PATCH] MD - Don't "analyze_sb" when creating new array.

Don't "analyze_sb" when creating new array.

When creating a new array (and we have an mddev->sb),
don't both to analyze the superblocks.  There is no point.
Also, these means we always allocate the array sb in
analyze_sbs, rather than conditionally.
