net: bridge: don't cache ether dest pointer on input
We would cache ether dst pointer on input in br_handle_frame_finish but after the neigh suppress code that could lead to a stale pointer since both ipv4 and ipv6 suppress code do pskb_may_pull. This means we have to always reload it after the suppress code so there's no point in having it cached just retrieve it directly.
