qcacld-3.0: Use pm_qos only at high bandwidth

Browse Source 
Currently we use PM qos apis to set masks and latency values at
PLD_BUS_WIDTH_LOW throughput level. As per experiments and power
measurements, this can also be done at the PLD_BUS_WIDTH_MEDIUM level
without any throughput impact and can help CPU enter C4 states at this
level.

Hence, donot use pm-qos APIs at less than high throughput levels.
