Ok, I checked this with a beagle board and it looks like that it's
caused by the firmware marking some packets received during scanning as
being received from 5 GHz band. After some testing I have pinpointed the
problem being caused by the firmware nvs file used. It's just annoying
that those errors are being emitted when scanning. I suppose that the
message could be changed from "ERROR" to "WARNING".
