These look fine to me, modulo the comments already made by Eric and
Serge.

You could further replace the remaining secondary_ops calls with direct
cap_ calls, since the dummy module is gone and the secondary module can
only be the capability module.  Smack and AppArmor already do this, I
believe.

At that point secondary_ops would only be used by selinux_init() to save
the original security_ops pointer for use by selinux_disable() to
restore the original pointer, which ideally would be handled by the
security framework instead (possibly by restoring a limited
unregister_security() that resets to the default_security_ops).
