Xuelin Shi e411566e7d dmaengine: fix dmaengine_unmap failure
commit c1f43dd9c2 upstream.

The count which is used to get_unmap_data maybe not the same as the
count computed in dmaengine_unmap which causes to free data in a
wrong pool.

This patch fixes this issue by keeping the map count with unmap_data
structure and use this count to get the pool.
