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.
