[ Upstream commitd85f017758] The ctx->sk_write_space pointer is only set when TLS tx mode is enabled. When running without TX mode its a null pointer but we still set the sk sk_write_space pointer on close(). Fix the close path to only overwrite sk->sk_write_space when the current pointer is to the tls_write_space function indicating the tls module should clean it up properly as well.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
