ath5k: remove ts_retry from ath5k_tx_status
Reusing the configured retry counts from the skb cb is more efficient than reloading the data from uncached memory. Replace ts_longretry (unused) with ts_final_retry which contains the retry count for the final rate only Signed-off-by: Felix Fietkau <nbd@openwrt.org> Signed-off-by: John W.
