IB/core: fix unmap_sg argument
__ib_umem_release calls dma_unmap_sg with a different number of
sg_entries than ib_umem_get uses for dma_map_sg. This might cause
trouble for implementations that merge sglist entries and results
in the following dma debug complaint:
DMA-API: device driver frees DMA sg list with different entry
count [map count=2] [unmap count=1]
Fix it by using the correct value.
