[XFS] Ensure errors from xfs_bdstrat() are correctly checked.
xfsbdstrat() is declared to return an error. That is never checked because
the error is propagated by the xfs_buf_t that is passed through the
function.
Mark xfsbdstrat() as returning void and comment the prototype on the
methods needed for error checking.
