Ming Lei fe73fbe1c5 lib/dma-debug.c: fix __hash_bucket_find() 
If there is only one match, the unique matched entry should be returned.

Without the fix, the upcoming dma debug interfaces ("dma-debug: new
interfaces to debug dma mapping errors") can't work reliably because
only device and dma_addr are passed to dma_mapping_error().
