WPS: Fix parsing of 0-length WFA vendor extension subelement

Browse source 
The previous parser would have skipped a WFA vendor extension attribute
that includes only a single zero-length subelement. No such subelement
has been defined so far, so this does not really affect any
functionality, but better make the parser address this correctly should
such an element ever be added.
