Subject: [PATCH net-next 4/7] net: dsa: felix: drop the ptp_type argument from felix_check_xtr_pkt()

The DSA ->port_rxtstamp() function is never called for PTP_CLASS_NONE:

dsa_skb_defer_rx_timestamp:

	if (type == PTP_CLASS_NONE)
		return false;

	if (likely(ds->ops->port_rxtstamp))
		return ds->ops->port_rxtstamp(ds, p->dp->index, skb, type);

So practically, the argument is unused, so remove it.
