The bytes_compl and pkts_compl pointers passed to efx_dequeue_buffers cannot be NULL. Add a paranoid warning to check this condition and fix the one case where they were NULL. efx_enqueue_unwind() is called very rarely, during error handling. Without this fix it would fail with a NULL pointer dereference in efx_dequeue_buffer, with efx_enqueue_skb in the call stack.
