qcacld-3.0: Set PM_QOS for non-offloaded TX at V_HIGH

Set system PM_QOS with low latency only for "very-high" throughput levels
in TX case. Currently, its being done for "high" throughput levels.
In less than "very-high" throughput cases, this allows CPU cores to
enter low power modes. This is done only for non-offloaded packets e.g.
UDP.
