Fix Bug 7340 Unable to apply modify firewall to interface when zone policy exists

* change commit check to only check if the interface being applied firewall ruleset
  is in a zone if only the ruleset type is either name|ipv6-name. Thus, ignoring the
  check when modify rule-set is being applied to an interface
