Drivers are expected to set the PHY current_channel and current_page according to their default state. The hwsim driver is advertising being configured on channel 13 by default but that is not reflected in its own internal pib structure. In order to ensure that this driver consider the current channel as being 13 internally, we at least need to set the pib->channel field to 13.
