bridge: stp: ensure mac header is set
commit bf9ae5386bca8836c16e69ab8fdbe46767d7452a
(llc: use dev_hard_header) removed the
skb_reset_mac_header call from llc_mac_hdr_init.
This seems fine itself, but br_send_bpdu() invokes ebtables LOCAL_OUT.
We oops in ebt_basic_match() because it assumes eth_hdr(skb) returns
a meaningful result.
