[PATCH 3/5] tmpfs: handle MPOL_LOCAL mount option properly

[KOSAKI Motohiro <kosaki.motohiro@jp.fujitsu.com>]

commit 71fe804b6d5 (mempolicy: use struct mempolicy pointer in
shmem_sb_info) added mpol=local mount option. but its feature is
broken since it was born. because such code always return 1 (i.e.
mount failure).

This patch fixes it.
