i3c_master_add_i3c_dev_locked() no longer leaves the address marked as free on failure, so aborting the DAA sequence on its error is unnecessary. Failure to register a discovered device does not invalidate the entire Dynamic Address Assignment (DAA) procedure. Align with the behavior of other I3C master drivers by ignoring errors from i3c_master_add_i3c_dev_locked() and continuing enumeration.
