[PATCH 08/14] net: vlan: remove invalid VLAN protocol warning

[Felix Fietkau <nbd@nbd.name>]

On MTK SoC ethernet, using NETIF_F_HW_VLAN_CTAG_RX in combination with hardware
special tag parsing can pass the special tag port metadata as VLAN protocol ID.
When the results is added as a skb hwaccel VLAN tag, it triggers a warning from
vlan_do_receive before calling the DSA tag receive function.
Remove this warning in order to properly pass the tag to the DSA receive function,
which will parse and clear it.
