Subject: [PATCH net-next] net: bridge: fix undefined br_vlan_can_enter_range in tunnel code

If bridge vlan filtering is not defined we won't have
br_vlan_can_enter_range and thus will get a compile error as was
reported by Stephen and the build bot. So let's define a stub for when
vlan filtering is not used.

Fixes: 94339443686b ("net: bridge: notify on vlan tunnel changes done via the old api")
Reported-by: Stephen Rothwell <sfr@...b.auug.org.au>

I mixed br_netlink_tunnel with br_vlan_tunnel where the former is always
compiled and the latter only with vlan filtering enabled.
