reiserfs: Add missing calls to reiserfs_security_free()

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.
