frr: T6023: add pending upstream patches

Latest stable/9.0 FRR branch has an updated version of frr-reload.py which
is more strict on the commands to remove from the running config. This resulted
in some issues in the codebase of FRR which are addressed in the attached patches
and are pending for upstream integration.

+Subject: [PATCH] ospfd: add support for "no router-info [<area|as>] command"
+
+frr-reload.py will walk through all config contexts and prepend no to the CLI
+command. This requires that the vtysh shell code accepts a full command.
+
+To Reproduce
+
+vtysh -c "conf t" -c "router ospf" -c "router-info area"
+vtysh -c "conf t" -c "router ospf" -c "no router-info area"
+% Unknown command: no router-info area
+vtysh -c "conf t" -c "router ospf" -c "no router-info"
