Log Message:
make dma flushing more efficient and avoid stray interrupts when not using polled io.
remove check for normal chaining interrupts and add check for combined chaining interrupts
only when used with a tail chain.  This allows scsi to work for short unaligned buffers
and large aligned buffers.
