[patch 1/5] r8169: missing netif_poll_enable and irq ack

[Francois Romieu <romieu@xxxxxxxxxxxxx>]

- (noticed by Jon D. Mason) rtl8169_wait_for_quiescence() needs to disable
  the NAPI processing but it has no reason to lock any part of the driver
  which would try to do the same at a later time. Let's reenable NAPI
  processing as soon as possible.
- properly ack any aborted interruption: a reset of the device is not
  always enough.
