Julian Wiedmann af9b4ab6ee s390/qeth: fix L2 header access in qeth_l3_osa_features_check()
[ Upstream commit f9c4845385 ]

ip_finish_output_gso() may call .ndo_features_check() even before the
skb has a L2 header. This conflicts with qeth_get_ip_version()'s attempt
to inspect the L2 header via vlan_eth_hdr().

Switch to vlan_get_protocol(), as already used further down in the
common qeth_features_check() path.

Fixes: f13ade1993 ("s390/qeth: run non-offload L3 traffic over common xmit path")
