Currently subflow_finish_connect() changes unconditionally
any msk socket status other than TCP_ESTABLISHED.
If an unblocking connect() races with close(), we can end-up
triggering:
IPv4: Attempt to release TCP socket in state 1 00000000e32b8b7e
when the msk socket is disposed.
Be sure to enter the established status only from SYN_SENT.
Fixes: c3c123d16c ("net: mptcp: don't hang in mptcp_sendmsg() after TCP fallback")

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.
