Subject[PATCH 3.2 17/61] drm/ttm: Fix accounting error when fail to get pages for pool
3.2.96-rc1 review patch.  If anyone has any objections, please let me know.

------------------

From: "Xiangliang.Yu" <Xiangliang.Yu@amd.com>

commit 9afae2719273fa1d406829bf3498f82dbdba71c7 upstream.

When fail to get needed page for pool, need to put allocated pages
into pool. But current code has a miscalculation of allocated pages,
correct it.
