Currently __mptcp_tcp_fallback() always return NULL on incoming connections, because MPTCP does not create the additional socket for the first subflow. Since the previous commit no __mptcp_tcp_fallback() caller needs a struct socket, so let __mptcp_tcp_fallback() return the first subflow sock and cope correctly even with incoming connections.

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.
