ath9k: fix ath_get_rate_txpower() to respect the rate list end tag

Stop reading (and copying) from ieee80211_tx_rate to ath_tx_info.rates
after list end tag (count == 0, idx < 0), prevents copying of garbage
to card registers.

Note: no need to write to the remaining ath_tx_info.rates entries
as the complete ath_tx_info struct is already initialized to zero from
both call sites.
