Roberto Sassu 582f5fc2c5 reiserfs: Add missing calls to reiserfs_security_free() 
commit 572302af1258459e124437b8f3369357447afac7 upstream.

Commit 57fe60df62 ("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.

Fixes: 57fe60df62 ("reiserfs: add atomic addition of selinux attributes during inode creation")

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.
