iface match: Unspecified matched interfaces should not log driver fails

Browse Source 
If there is no matching interface given, but interface matching is
enabled, all interfaces on the system will try to be initialized. Non
wireless interfaces will fail and the loopback device will be one of
these, so just log a diagnostic rather than an error.
