ocfs2: free allocated clusters if error occurs after ocfs2_claim_clusters
Even if using the same jbd2 handle, we cannot rollback a transaction.
So once some error occurs after successfully allocating clusters, the
allocated clusters will never be used and it means they are lost. For
example, call ocfs2_claim_clusters successfully when expanding a file,
but failed in ocfs2_insert_extent. So we need free the allocated
clusters if they are not used indeed.
