ehea: Fix TSO and hw checksums with non-accelerated vlan packets.
The driver claims that it can do TSO and IP checksums on vlan
devices and also allows user to control vlan acceleration offloading.
This makes it possible to push traffic to this driver that has TSO or
partial checksums set, but also have a non-accelearted vlan
header. In this case, the driver will fail to correctly
identify such traffic and will not correctly perform
segmentation and checksum calculation.
Fix this by using vlan_get_protocol() helper instead of
assuming skb->protocol always has this information.
