mac_dbdma: Remove leftover `dma_memory_unmap` calls
These were passing a NULL buffer pointer unconditionally, which happens
to behave in a mostly benign way (except for the chance of an excess
memory region unref and a bounce buffer leak). Per the function comment,
this was never meant to be accepted though, and triggers an assertion
with the "softmmu: Support concurrent bounce buffers" change.
Given that the code in question never sets up any mappings, just remove
the unnecessary dma_memory_unmap calls along with the DBDMA_io struct
fields that are now entirely unused.
