Could you please provide an example configuration and hostapd debug log
showing this? I'm not sure how it would be possible to get into
radius_client_get_mib() with radius == NULL since this parameter comes
from hapd->radius and that pointer is required to be non-NULL when a BSS
is operational. This is the case regardless of whether there are
configured RADIUS servers.
