DMA synchronization fixes:

 - In bce_rx_intr(), use BUS_DMASYNC_POSTREAD instead of
   BUS_DMASYNC_POSTWRITE, as we want to "read" from the
   rx page chain pages.
 - Document why we need to do PREWRITE after we have updated
   the rx page chain pages.
 - In bce_intr(), use BUS_DMASYNC_POSTREAD and
   BUS_DMASYNC_PREREAD when before and after CPU "reading"
   the status block.
 - Adjust some nearby style mismatches/etc.
