Data frames sent over the mgmt path might be part of a TX aggr session

too. In that case don't fiddle with the seqno as drivers are supposed
to handle that.

Currently only the powersave feature does sent QoS-null-data frames
before and after a background scan which must be handled correctly. Due
to this being quite rare we don't fiddle around with starting of aggr
sessions.
