OSPF: skip interfaces without OSPF enabled

Fix a bug where systems with OSPF enabled on some, but not all,
interfaces would cause the OSPF iterator to fail when accessing
iface['area'], which was missing. This caused the ospf_status.py
tool to return {}, resulting in empty OSPF data in sysrepo.

Fixes #1169 Expected neighbors not shown in sysrepocfg
