[RFC][PATCH 06/20] cad_pid: Fixup the cad_pid users to assume it is in the initial process id namespace.

[ebiederm@xmission.com (Eric W. Biederman)]

Having the kernel memorize pids of running processes is ugly.  Especially if
those processes are allowed to exit.  So we don't introduce any lifetime issues
or any other weird uglyness and simply insist that the cad_pid is always
interpreted with respect to the initial process id namespace.
