Iwinfo: ath10k driver not working

Hi,
the athk10 driver and the iwinfo lib seems not to work correctly.
I wanted to implement the channel utilization call in this branch.
For the ath9k everything works fine. But for the ath10k the result is always 0 for different values.

iw wlan0 survey dump

is working...

I made it work.

Leave a break between two surveys... :slight_smile:
