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.
