Subject: [PATCH net-next] r8169: reconfigure rx unconditionally before chip
 reset when resuming

There's a good chance that more chip versions suffer from the same
hw issue. So let's reconfigure rx unconditionally before the chip reset
when resuming. This shouldn't have any side effect on unaffected chip
versions.
