[PATCH] ttm: Do not increment the amount of pages in a pool by the current amount

[Konrad Rzeszutek Wilk <konrad.wilk@oracle.com>]

.instead increment it by the count of pages that we want to
splice into the pool list.

In other words we were incrementing the pool->npages by the wrong
amount. This bug was observed from code inspection.
