[collectd] [PATCH] Fix a number of minor bugs.

[Andres J. Diaz]

- The Port configuration option is a string, not a number. Fix
  documentation.

- Fix a bad status assignement in port parser.

- Remove default node. Now node is mandatory to prevent
  duplicates in tree.

- Update configuration example too.
