    igc: fix RX accounting for multi-descriptor packets
    
    The receive path adds the running packet length to rx_bytes for every
    descriptor.  A packet spanning descriptors of length l1, l2, and l3 is
    therefore counted as 3*l1 + 2*l2 + l3.
    
    Add each descriptor length once.  Single-descriptor accounting remains
    unchanged.
