Description (partial)

This issue was found on 5.2.2 after RIB hot standby feature was introduced, however this issue can be triggered before 5.2.2 given a timing condition where rsi_agent callback to open the connection to that vrf came late.

Symptom:
The configured maximum prefix limit is not applied after process restart ipv4_rib

Conditions:
1, Before 5.2.2
2, maximum prefix limit configured
3, rsi_conn_open callback came late during rib startup
    (One trigger can be process restart rsi_agent and ipv4_rib in a tight schedule)
