Regression in hid-sensor-hub

Commit d443a0aa3a291e5f78072f2fa464e03bc83fafad (HID: hid-sensor-hub:
clear memory to avoid random data) stops screen rotation from working on my Lenovo Thinkpad X1 Yoga using iio-sensor-proxy. Reverting this commit restores function.

See bug at https://github.com/hadess/iio-sensor-proxy/issues/124

I'd be happy to provide more info if someone tells me what to provide!

Cheers,
Rann
