qdpc-host: use Comcerto PFE fastpath.
- If CONFIG_ARCH_COMCERTO=y, allocate SKBs on NCNB memory and pass
received packets to comcerto_wifi_rx_fastpath().
- Change default interface name pattern from host%d to wlan%d. This
allows fastforward.config to work without modifications.
- Change NAPI budget from 10 to 64.
These changes enable Optimus Prime to forward packets at over 1Gbps.
