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.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
