This code fix a bug that sk->sk_txrehash gets its default enable
value from sysctl_txrehash only when the socket is a TCP listener.
We should have sysctl_txrehash to set the default sk->sk_txrehash,
no matter TCP, nor listerner/connector.
Tested by following packetdrill:
0 socket(..., SOCK_STREAM, IPPROTO_TCP) = 3
+0 socket(..., SOCK_DGRAM, IPPROTO_UDP) = 4
// SO_TXREHASH == 74, default to sysctl_txrehash == 1
+0 getsockopt(3, SOL_SOCKET, 74, [1], [4]) = 0
+0 getsockopt(4, SOL_SOCKET, 74, [1], [4]) = 0

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.
