Commit 57fe60df6241 ("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.
