Revert "qcacld-2.0: Implement get_wireless_stats IOCTL"
This reverts commit I4239fff2098800968e5961443186277d8b79062d
When chariot tx traffic is run, almost for every 7 ms there is
invocation of get_wireless_stats IOCTL and leading to higher
inactive times, thereby reduce in tx performance.
To avoid this, previous commit corresponding to IOCTL add is removed.
