r8169: adjust the flow of hw_start

The suggestion as following:
- initial settings or default settings
- rtl_hw_start_xxx. rtl_hw_start_xxx may change some default settings.
- enable tx/rx. This has to be after the above two steps.
- rtl_set_rx_mode. AcceptXXXs have to be enabled after enabling tx/rx.
