Loic Poulain efc36d3c34 net: mhi: Fix unexpected queue wake
This patch checks that MHI queue is not full before waking up the net
queue. This fix sporadic MHI queueing issues in xmit. Indeed xmit and
its symmetric complete callback (ul_callback) can run concurently, it
is then not safe to unconditionnaly waking the queue in the callback
without checking queue fullness.

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.
