mac80211: Update last_tx_rate only for data frames
The last_tx_rate field was also updated for non-data frames that are often sent with a lower rate (for example management frames at 1 Mbps). This is confusing when the data rate is actually much higher. Hence, only update the last_tx_rate field with tx rate information gathered from last data frames. If the rate control algorithm filled in txrc.reported_rate we don't need to verify this information.
