set_interface of cisco.ios.ios_ospfv2 module is un-idempotent

[startryst]

SUMMARY

For first time to setup passive interface on OSPF, set_interface is needed, take below for example:

ospf_passive_interfaces:
  set_interface: true
  name:
    - GigabitEthernet1

but when ran the second or more time of the same playbook, it always shows as changed, even though the config is not changed:

    "router ospf 1"
