Commit57fe60df62("reiserfs: add atomic addition of selinux attributes during inode creation") defined reiserfs_security_free() to free the name and value of a security xattr allocated by the active LSM through security_old_inode_init_security(). However, this function is not called in the reiserfs code. Thus, add a call to reiserfs_security_free() whenever reiserfs_security_init() is called, and initialize value to NULL, to avoid to call kfree() on an uninitialized pointer. Finally, remove the kfree() for the xattr name, as it is not allocated anymore.

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.
