md-cluster/bitmap: fix wrong calcuation of offset
The offset is wrong in bitmap_storage_alloc, we should
set it like below in bitmap_init_from_disk().
node_offset = bitmap->cluster_slot * (DIV_ROUND_UP(store->bytes, PAGE_SIZE));
Because 'offset' is only assigned to 'page->index' and
that is usually over-written by read_sb_page. So it does
not cause problem in general, but it still need to be fixed.
