Ocfs2/refcounttree: Fix a bug for refcounttree to writeback clusters in a right number.
Current refcounttree codes actually didn't writeback the new pages out in
write-back mode, due to a bug of always passing a ZERO number of clusters
to 'ocfs2_cow_sync_writeback', the patch tries to pass a proper one in.
