IB/core: Fix mismatch between locked and pinned pages
Commit bc3e53f682d9 ("mm: distinguish between mlocked and pinned pages") introduced a separate counter for pinned pages and used it in the IB stack. However, in ib_umem_get() the pinned counter is incremented, but ib_umem_release() wrongly decrements the locked counter. Fix this.
