[PATCH] net: dsa: fixup fail to get tag in mtk_get_tag_protocol

[<sean.wang@mediatek.com>]

From: Sean Wang <sean.wang@mediatek.com>

dsa_is_cpu_port() checking ds->cpu_port_mask is not available in
ds->ops->get_tag_protocol

Since commit 14be36c2c96c ("net: dsa: Initialize all CPU and enabled
ports masks in dsa_ds_parse()") So force returning DSA_TAG_PROTO_MTK
inside mtk_get_tag_protocol call after that.
