ntfs3: fix double free of sbi->options->nls and clarify ownership of fc->fs_private
commit 02f312754c ("ntfs3: fix use-after-free of sbi->options in cmp_fnames") introduced a use-after-free bug
due to improper handling of sbi->options in error paths. This resulted in crashes when superblock cleanup
is performed in ntfs_put_super.

This patch ensures that the options structure and its subfields are properly freed, preventing the memory
corruption and use-after-free errors.

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.
