doc: always use 'None' for functions not returning a value

Browse Source 
It is preferred to state the absence of a return value explicitly in the
doxygen-stile comments. Currently there are different styles of doing this,
including:

  @return None
  @return NULL
  @return void
  @return N/A

This patch unifies the above with `@return None`.
