thorpej e2a2842013 Keep track of which DMA window was actually used to map the
request (not always the passed in DMA tag if we try direct-map
and then fall back to sgmap-mapped).  Use the actual window
when performing dmamap_sync and dmamap_unload operations.

Fixes DMA resource leak on systems with 2G+ RAM.  Thanks to
Matt Thomas for help debugging this.
