qcacld-3.0: Check consistency in throughput before setting delack
Integration from cld-2.0 to cld-3.0.
Currently the throughput is measured every 100 ms. Delack is set to 20
if throughput for this interval is greater then threshold (~57 Mbps).
In the case of congestion control, tcp may take longer duration for
rampup. In this change, throughput is checked for consistency for
about three seconds and then tcp delack is set to 20.
