fs/ntfs3: Fix memory leak on ntfs_fill_super() error path 
syzbot reported kmemleak as below:

BUG: memory leak
unreferenced object 0xffff8880122f1540 (size 32):

This patch fixes this issue by freeing mount options on error path of
ntfs_fill_super().

README 

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.
