ath9k: fix invalid descriptor discarding
Only set sc->rx.discard_next to rx_stats->rs_more when actually
discarding the current descriptor.
Also, fix a detection of broken descriptors:
First the code checks if the current descriptor is not done.
Then it checks if the next descriptor is done.
Add a check that afterwards checks the first descriptor again, because
it might have been completed in the mean time.
This fixes a regression introduced in
