netfilter: nf_tables: fix potential oops when dumping sets Commit c9c8e48597 (netfilter: nf_tables: dump sets in all existing families) changed nft_ctx_init_from_setattr() to only look up the address family if it is not NFPROTO_UNSPEC. However if it is NFPROTO_UNSPEC and a table attribute is given, nftables_afinfo_lookup() will dereference the NULL afi pointer. Fix by checking for non-NULL afi and also move a check added by that commit to the proper position.
