Lee Jones fb29f6bbe4 nfc: llcp: Fix use-after-free in llcp_sock_release() 
[ Upstream commit f4268b4661 ]

llcp_sock_release() unconditionally unlinks the socket from the local
sockets list.  However, if the socket is still in connecting state, it
is on the connecting list.

Fix this by checking the socket state and unlinking from the correct list.

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.
