md/md-bitmap: add a new helper md_bitmap_set_pages()
Currently md-cluster will set bitmap->counts.pages directly, add a
helper to do this to avoid dereferencing bitmap directly.
Noted that after this patch bitmap is not dereferenced directly anymore
and following patches will move the structure inside md-bitmap.c.
