Newer firmware versions will support a new queue allocation
command, in order to deal with MLD where multiple stations
are used for a single queue. Add support for the new command.

This requires some refactoring of the queue allocation API,
which now gets
 - the station mask instead of the station ID
 - the flags without the "enable" flag, since that's no longer
   used in the new API

Additionally, this new API now requires that we remove queues
before removing a station, the firmware will no longer do that
internally. Also add support for that.

A scan during active P2P GO operation, i.e., data traffic with
clients, can impact the throughput and latency of such traffic.
Thus, when scan is requested while there is an active P2P GO
and low latency is asserted:

- Ask the FW scan logic to respect the P2P GO activity during the
  scheduling of the scan operation to minimize the impact on the
  throughput and latency.
- Force scan to perform EBS before starting the scan to reduce the
  number of scanned channels.

Non PSC channels should generally be scanned based on information about
collocated APs obtained during scan on legacy bands, and otherwise
should not be scanned unless specifically requested so (as there are
relatively many non PSC channels, scanning them passively is time consuming
and interferes with regular data traffic).

Thus, modify the scan logic to avoid passively scanning PSC channels
if there is no information about collocated APs and the scan is not
a passive scan.
