[ Upstream commit f70cad1085d1e01d3ec73c1078405f906237feee ] We want to revert the skb TX cache, but MPTCP is currently using it unconditionally. Rework the MPTCP tx code, so that tcp_tx_skb_cache is not needed anymore: do the whole coalescing check, skb allocation skb initialization/update inside mptcp_sendmsg_frag(), quite alike the current TCP code.

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 Restructured Text 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.
