Stanislav Sedov 15eda8010b - On entrance to the rx_eof sync RX rings maps with POSTWRITE flag
instead of POSTREAD: the hardware do not touch this memory (CPU
  updates it).  It is already synchronized as PREWRITE after the
  processing is done.

- Synchronize RX return ring memory in rx_eof.  This is needed
  as the deviced updates this memory when receives packets.

- Decouple the synchronization of BGE status block in the interrupt
  service routine: perfrom PREREAD synchronization only all accesses
  to this block are finished.  This seems to be more natural.
