Log:
  Don't calltsec_receive_intr_locked() from the error interrupt handler.
  
  The tsec_error_intr_locked() is called with the global lock owned (e.g.
  the transmit and the receive lock are both owned).  We must not call
  tsec_receive_intr_locked() while owning the transmit lock.  The normal
  receive interrupt takes care that frames are received, this is none of
  the business of the error interrupt.
