[PATCH v2 1/3] sched: fix confusing PFA_NO_NEW_PRIVS constant

From: Zefan Li
Date: Mon Sep 22 2014 - 00:44:35 EST

Commit 1d4457f99928 ("sched: move no_new_privs into new atomic flags")
defined PFA_NO_NEW_PRIVS as hexadecimal value, but it is confusing
because it is used as bit number. Redefine it as decimal bit number.

Note this changes the bit position of PFA_NOW_NEW_PRIVS from 1 to 0.
