qcacld-3.0: Move buckets_scanned mask for extscan get cache result

qcacld-2.0 to qcacld-3.0 propagation

If host issues extscan get cache results, while gscan is not in
progress then buckets_scanned mask comes as zero. To handle this
issue now firmware sends the buckets_scanned mask as part of
wmi_extscan_rssi_info instead of fixed_param.
