qcacld: Add "rssi" support to device ioctl handler hdd_ioctl()

The "rssi" command is currently supported by the wireless extensions
private command handler, but is not supported by the device ioctl
handler hdd_ioctl(). Add this command to hdd_ioctl() so that we can
wean folks from wireless extensions.
