config: suppress error if no wireless config present (FS#1030)

Wireless config is optional as not all targets have a wireless interface;
therefore don't report an error if the wireless config is missing so
network reload is not reporting an error to the user.
While at it use netifd_log_message to print an error if the config cannot
be loaded.
