coroparse: Handle end of special sections

Special sections totem.interface, logging.logger_subsys,
logging.logging_daemon and nodelist.node executes extra code on end of
section. Previously, any end of section triggered handling, including
subsection one.

So for example config like:
```
nodelist {
  node {
    name: node1
    subs {
      key: val
    }
  }

  node {
    name: node2
    ...
```

result in node_number increased twice (once for end of "subs" section
and second time for end of "node" section) so node2 got number 2 instead
of 1.

Same was happening for all other special sections and may result in
crash as reported by vikk777 <listratenko1998@mail.ru> in
issues #783 and #784.

Solution is to execute extra code only for real end of section and not
for subsection.

This patch fixes only main problem but it creates keys without
subsection name what is not optimal.
