rt2800: do VCO calibration after programming ALC

dangowrt · Kalle Valo · commit 2031badabf26 · 2017-04-20T14:00:00.000+03:00
Somehow AP doesn't come up and the first scan fails if we don't do
VCO calibration every time.
The vendor driver duplicates the VCO calibration function into the
channel switching logic, we can do the same with less duplication.
