Andrei Vagin reported that blamed commit broke CRIU.
Indeed, while we want to keep sk_uid unchanged when a socket
is cloned, we want to clear sk->sk_ino.
Otherwise, sock_diag might report multiple sockets sharing
the same inode number.
Move the clearing part from sock_orphan() to sk_set_socket(sk, NULL),
called both from sock_orphan() and sk_clone_lock().

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 reStructuredText 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.
