ice: add useful statistics
Display and count some useful hot-path statistics. The usefulness is as
follows:
- tx_restart: use to determine if the transmit ring size is too small or
if the transmit interrupt rate is too low.
- rx_gro_dropped: use to count drops from GRO layer, which previously were
completely uncounted when occurring.
- tx_busy: use to determine when the driver is miscounting number of
descriptors needed for an skb.
- tx_timeout: as our other drivers, count the number of times we've reset
due to timeout because the kernel only prints a warning once per netdev.
Several of these were already counted but not displayed.
