don't use fd for matching DMA region for unmap

The fd might come from another process so it doesn't make sense, the IOVA range
alone is sufficient to determine the DMA region to unmap.

Also, don't fail unmapping DMA regions that don't exist. Maybe we should revisit
this and ignore the error at the client side?
