Until now, wfx_flush() flushed queue for while device instead of only the queue of the intended vif. It sometime failed with a timeout, but this error was not reported. Moreover, if the device was frozen, wfx_flush didn't do anything and it results a potential warning (and maybe a resource leak) when the frozen device was unregistered. We can also notice that wfx_tx_queues_wait_empty_vif() did only exist to work around the broken feature of wfx_flush(). This patch repair wfx_flush() and therefore drop wfx_tx_queues_wait_empty_vif().

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.
