Felix's patch is for Noise Floor calibration timeout which is
non-fatal, here we have a problem with gain offset calibration. If
gain offset calibration fails, we can't have i/q correction and we
can't tune to that channel propertly.

This is a known problem also reported on binary HAL ;-)

we miss something in rf/phy initialization i guess...
