Subject: [PATCH v8 3/6] security: Remove security_old_inode_init_security()

From: Roberto Sassu <roberto.sassu@...wei.com>

As the remaining two users reiserfs and ocfs2 switched to
security_inode_init_security(), security_old_inode_init_security() can be
now removed.

Out-of-tree kernel modules should switch to security_inode_init_security()
too.
