yuan linyu 0ecc97c81e usb: f_mass_storage: forbid async queue when shutdown happen 
commit b2d2d7ea0d upstream.

When write UDC to empty and unbind gadget driver from gadget device, it is
possible that there are many queue failures for mass storage function.

The root cause is mass storage main thread alaways try to queue request to
receive a command from host if running flag is on, on platform like dwc3,
if pull down called, it will not queue request again and return
-ESHUTDOWN, but it not affect running flag of mass storage function.

Check return code from mass storage function and clear running flag if it
is -ESHUTDOWN, also indicate start in/out transfer failure to break loops.

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.
