sched/debug: Remove mpol_get/put and task_lock/unlock from sched_show_numa
[ Upstream commit 28c988c3ec29db74a1dda631b18785958d57df4f ]
The older format of /proc/pid/sched printed home node info which
required the mempolicy and task lock around mpol_get(). However
the format has changed since then and there is no need for
sched_show_numa() any more to have mempolicy argument,
asssociated mpol_get/put and task_lock/unlock. Remove them.
