[M118-Extensions] Don't update access if site permissions aren't allowed

Page access options in the extension's context menu should only be
enabled when the extension site permissions can be changed. However, sometimes the command still gets invoked (crbug.com/1468151). Thus, we
exit early to prevent any crashes.
