Enhance IP filtering to allow multiple USB vNIC IPs

Updated `isAllowedIP()` to support both 192.168.31.1 and 192.168.31.2
as valid USB vNIC IP addresses.

Clean up: Removed redundant error log

Tests:
Redfish event gereration from USB vNIC ip "192.168.31.2" is success
Able to view the redfish event in bmcweb.
