Florian Westphal 46df417544 netfilter: nf_tables: do not store rule in traceinfo structure
pass it as argument instead.  This reduces size of traceinfo to
16 bytes.  Total stack usage:

 nf_tables_core.c:252 nft_do_chain    304     static

While its possible to also pass basechain as argument, doing so
increases nft_do_chaininfo function size.

Unlike pktinfo/verdict/rule the basechain info isn't used in
the expression evaluation path. gcc places it on the stack, which
results in extra push/pop when it gets passed to the trace helpers
as argument rather than as part of the traceinfo structure.
