Paolo Abeni suggested to avoid re-syncing new subflows because they inherit options from listener. In case options were set on listener but are not set on mptcp-socket there is no need to do any synchronisation for new subflows. This change sets sockopt_seq of new mptcp sockets to the seq of the mptcp listener sock. Subflow sequence is set to the embedded tcp listener sk. Add a comment explaing why sk_state is involved in sockopt_seq generation.

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.
