xfs: add a proper transaction pointer to struct xfs_buf
Replace the typeless b_fspriv2 and the ugly macros around it with a properly typed transaction pointer. As a fallout the log buffer state debug checks are also removed. We could have kept them using casts, but as they do not have a real purpose we can as well just remove them.
