ath9k: fix duration calculation for non-aggregated packets
When not aggregating packets, fi->framelen should be passed in as length to calculate the duration. Before the tx path rework, ath_tx_fill_desc was called for either one aggregate, or one single frame, with the length of the packet or the aggregate as a parameter. After the rework, ath_tx_sched_aggr can pass a burst of single frames to ath_tx_fill_desc and sets len=0. Fix broken duration calculation by overriding the length in ath_tx_fill_desc before passing it to ath_buf_set_rate.
