Currently, wfx_do_unjoin() are called by the mean of work queues.
However, the contexts from where they are called are not atomic. So
there is no reason to not call it synchronously.
This change will simplify the code. Notice two main changes:
- There no more reason to lock tx queue before to run
wfx_do_unjoin(). We can lock the tx queue directly from
wfx_do_unjoin().
- Most of the time, wfx_do_unjoin_work() was called with conf_mutex
held. This patch remove lock of conf_mutex in wfx_do_unjoin_work()
and ensure that conf_mutex is always held whatever the context.

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.
