Then the solution is simple:

        for_each_bank()
                if (log_error()) {
                        clear_msrs();
                        continue;
                }

                if (mca_cfg.smca) {
                        log_error_from_de_regs()
                        clear_msrs();
                }
        }

and clear_msrs() clears them all.
