team: Fix incorrect deletion of ETH_P_8021AD protocol vid from slaves
Similar to commit 01f4fd270870 ("bonding: Fix incorrect deletion of
ETH_P_8021AD protocol vid from slaves"), we can trigger BUG_ON(!vlan_info)
in unregister_vlan_dev() with the following testcase:
# ip netns add ns1
# ip netns exec ns1 ip link add team1 type team
# ip netns exec ns1 ip link add team_slave type veth peer veth2
# ip netns exec ns1 ip link set team_slave master team1
# ip netns exec ns1 ip link add link team_slave name team_slave.10 type vlan id 10 protocol 802.1ad
# ip netns exec ns1 ip link add link team1 name team1.10 type vlan id 10 protocol 802.1ad
# ip netns exec ns1 ip link set team_slave nomaster
# ip netns del ns1
Add S-VLAN tag related features support to team driver. So the team driver
will always propagate the VLAN info to its slaves.
Fixes: 8ad227ff89a7 ("net: vlan: add 802.1ad support")
