Currently, PMK parameters in the WPA state machine are set from
configuration only when the interface is initialized. If those
parameters are changed later via D-Bus, the new values don't have any
effect.
Call wpa_sm_set_param() when PMK-related D-Bus properties are changed
to immediately apply the new value; the control interface also does
something similar.
