eth: fbnic: add coverage for hw queue stats
This patch provides support for hardware queue stats and covers
packet errors for RX-DMA engine, RCQ drops and BDQ drops.
The packet errors are also aggregated with the `rx_errors` stats in the
`rtnl_link_stats` as well as with the `hw_drops` in the queue API.
The RCQ and BDQ drops are aggregated with `rx_over_errors` in the
`rtnl_link_stats` as well as with the `hw_drop_overruns` in the queue API.
