bandwidth: Correct handling of RADIUS-assigned bandwidth

Browse Source 
limits

Description:
Hostapd successfully parsed the uplink and downlink bandwidth attributes from
the RADIUS server, but the values were not being propagated correctly into
sta_info. As a result, the bandwidth information was missing in the UBUS
events sent to ucentral-event.

Fix:
Ensure the parsed bandwidth values are correctly passed to sta_info so they
 are included in subsequent UBUS notifications.

Tests Performed:
Configured per-client bandwidth limits on the RADIUS server and verified that:

 - The AP enforces the configured uplink/downlink limits, and
 - The correct bandwidth values appear in the UBUS events.
