  Recollect TX/RX descriptors if we are going to switch back to TX/RX interrupts,
  mainly to avoid the _possible_ race between turning on TX/RX interrupts and
  asserting TX/RX interrupt by hardware.  Though nfe(4) does not seem to suffer
  the problem, which I have seen on re(4), we still apply the same fix here;
  better safe than sorry.
