qcacld-3.0: Disable early stop feature as per config

If early stop feature is disabled in the configuration,
then let the firmware know to disable it.
There is no WMI item to let firmware know about disabling
the feature explicitly.
Hence, set the roam_earlystop_thres_min and roam_earlystop_thres_max
to zero which the firmware uses to disable the feature.
