When stopping XDP TX rings, the XDP clean function needs to be called to
clean out the entire queue, similar to what happens in the normal TX
queue case. Otherwise, the FIFO won't be cleared correctly, and
xsk_tx_completed won't be reported.

Fixes: 75eaae158b1b ("gve: Add XDP DROP and TX support for GQI-QPL format")
