netfilter: nf_tables: allocate element update information dynamically
Move the timeout/expire/flag members from nft_trans_one_elem struct into
a dybamically allocated structure, only needed when timeout update was
requested.
This halves size of nft_trans_one_elem struct and allows to compact up to
124 elements in one transaction container rather than 62.
This halves memory requirements for a large flush or insert transaction,
where ->update remains NULL.
Care has to be taken to release the extra data in all spots, including
abort path.
