bridge: Fix br_should_learn to check vlan_enabled
As Toshiaki Makita pointed out, the BRIDGE_INPUT_SKB_CB will not be initialized in br_should_learn() as that function is called only from br_handle_local_finish(). That is an input handler for link-local ethernet traffic so it perfectly correct to check br->vlan_enabled here. Reported-by: Toshiaki Makita<toshiaki.makita1@gmail.com> Fixes: 20adfa1 bridge: Check if vlan filtering is enabled only once.
