Do not ignore Open vSwitch restart failures.

This restart is the cleanup fix. With || true, cleanup can return success while stale flow state remains, and the following MicroShift start can fail. Propagate the failure, or handle only a known unsupported-service case explicitly.

Proposed fix 
-        systemctl restart openvswitch.service 2>/dev/null || true
+        if ! systemctl restart openvswitch.service; then
+            echo "Failed to restart openvswitch.service" >&2
+            return 1
+        fi

In `@scripts/microshift-cleanup-data.sh` at line 114, Update the Open vSwitch
restart command in the cleanup script to propagate restart failures instead of
suppressing them with “|| true”; only handle an explicitly identified
unsupported-service case if required, while preserving normal cleanup failure
reporting.
