Remove mutex 'usb_vendor_req_mutex'. It was used to protect a shared buffer for USB requests and, since that buffer is removed in previous patch, this mutex is now useless. Furthermore, because it was used to serialize the calls to the Core USB API, we thoroughly tested the enabling of concurrent firing of USB requests without the mutex and found no problems of any kind in common use cases.

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.
