The "Server interfaces" count in /proc/fs/cifs/DebugData increases
as the interfaces are requeried, rather than being reset to the new
value. This could cause a problem if the server disabled
multichannel as the iface_count is checked in try_adding_channels
to see if multichannel still supported.
Also fixes a coverity warning:
Addresses-Coverity: 1526374 ("Concurrent data access violations (MISSING_LOCK)")

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.
