Apply error and success logic consistently to the function netisr_queue() and
its users. netisr_queue() now returns (0) on success and ERRNO on failure. At the moment ENXIO (netisr queue not functional) and ENOBUFS (netisr queue full) are supported. Previously it would return (1) on success but the return value of IF_HANDOFF() was interpreted wrongly and (0) was actually returned on success. Due to this schednetisr() was never called to kick the scheduling of the isr. However this was masked by other normal packets coming through netisr_dispatch() causing the dequeueing of waiting packets.
