kernel-doc: improve handling of whitespace on the first line param description
Handle whitespace on the first line of param text as if it was the empty string. There is no need to add the newline in this case. This improves the rst output in particular, where blank lines may be problematic in parameter lists. Signed-off-by: Jani Nikula <jani.nikula@intel.com>
