mod_scmi: Fix the number of SCMI notifications sent to an agent

SCMI notification should be sent to the subscribers for a specific operation on a specific resource. But, the current SCMI notification has a defect, it sends notification for a specific operation on any resource, resulting in sending same notification multiple times to the subscribers.

The looping around element/resource list in SCMI Notification table is redundant, hence omitted to fix the defect.
