dmaengine: fix dmaengine_unmap failure
commit c1f43dd9c20d85e66c4d77e284f64ac114abe3f8 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.
