netfilter: nf_tables: do not allow mismatch field size and set key length
[ Upstream commit 3ce67e3793f48c1b9635beb9bb71116ca1e51b58 ]
The set description provides the size of each field in the set whose sum
should not mismatch the set key length, bail out otherwise.
I did not manage to crash nft_set_pipapo with mismatch fields and set key
length so far, but this is UB which must be disallowed.
