bridge: Use direct pointer in br_is_nd_neigh_msg()

Both callers of br_is_nd_neigh_msg() already call pskb_may_pull() to
ensure sizeof(struct ipv6hdr) + sizeof(struct nd_msg) bytes are in the
linear area before invoking this function. The skb_header_pointer()
call and its fallback buffer are therefore unnecessary.

Replace skb_header_pointer() with a direct cast to ipv6_hdr(skb) + 1
and drop the now-unused 'msg' parameter and its corresponding stack
buffer from all callers.
