[ Upstream commit1a74e99323] Since commite5d5aadcf3("net/smc: fix sk_refcnt underflow on linkdown and fallback"), for a fallback connection, __smc_release() does not call sock_put() if its state is already SMC_CLOSED. When calling smc_shutdown() after falling back, its state is set to SMC_CLOSED but does not call sock_put(), so this patch calls it.

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.
