Currently the aggregation is formed till the aggregation limit

But there can be a legacy rated frames in tid queue. This patch
limits the subframe addition based on last MRR's rate and sends
the legacy rated frames as unaggregated one.

No it isn't. Maybe with ath9k_rate_control, but things may change with
other rate control modules.
