[Devel] [RFC][PATCH 12/14] Remove copy_pid_ns function

[sukadev at us.ibm.com]

From: Sukadev Bhattiprolu <sukadev at us.ibm.com>
Subject: [RFC][PATCH 12/14] Remove copy_pid_ns function

Remove the copy_pid_ns() function as we have decoupled pid namespace
from nsproxy and also because we currently disallow unsharing of pid
namespace.
