was being initialized to a KVA, when we really wanted a DMA address. Change the code to allocate the overrun buffer with the control blocks, and properly initialize overrun_buf. Note that overrun_buf cannot actually be shared between all boards; DMA safe memory could vary from bus to bus. Garbage-collect two functions which are no longer used because of the above changes.
