netfilter: nf_tables: fix nft_trans type confusion
nft_trans_FOO objects all share a common nft_trans base structure, but trailing fields depend on the real object size. Access is only safe after trans->msg_type check. Check for rule type first. Found by code inspection. Fixes: 1a94e38d ("netfilter: nf_tables: add NFTA_RULE_ID attribute") Signed-off-by:Florian Westphal <fw@strlen.de>
