Changwei Ge 3373de209c ocfs2: revert "ocfs2/o2hb: check len for bio_add_page() to avoid getting incorrect bio" 
This reverts commit ba16ddfbeb ("ocfs2/o2hb: check len for
bio_add_page() to avoid getting incorrect bio").

In my testing, this patch introduces a problem that mkfs can't have
slots more than 16 with 4k block size.

And the original logic is safe actually with the situation it mentions
so revert this commit.

Attach test log:
