When the clcsock is already released using sock_release() and a pending smc_listen_work accesses the clcsock than that will fail. Solve this by canceling and waiting for the work to complete first. Because the work holds the sock_lock it must make sure that the lock is not hold before the new helper smc_clcsock_release() is invoked. And before the smc_listen_work starts working check if the parent listen socket is still valid, otherwise stop the work early.

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.
