Konstantin Komarov c293e8abc0 fs/ntfs3: Fix missing i_op in ntfs_read_mft
commit 37a530bfe56ca9a0d3129598803f2794c7428aae upstream.

There is null pointer dereference because i_op == NULL.
The bug happens because we don't initialize i_op for records in $Extend.
Fixes: 82cae269cfa9 ("fs/ntfs3: Add initialization of super block")

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.
