During my experiments to make dlm robust against tcpkill application I was able to run sometimes in a circular lock dependency warning between clusters_root.subsys.su_mutex and con->sock_mutex. We don't need to held the sock_mutex when getting the mark value which held the clusters_root.subsys.su_mutex. This patch moves the specific handling just before the sock_mutex will be held.

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.
