netfilter: nf_tables: fix nft_trans type confusion

[ Upstream commit e3c361b8acd636f5fe80c02849ca175201edf10c ]

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.
