iwlwifi: mvm: support dqa-mode agg on non-shared queue
In non-shared queues, DQA requires re-configuring existing
queues to become aggregated rather than allocating a new
one. It also requires "un-aggregating" an existing queue
when aggregations are turned off.
Support this requirement for non-shared queues.
