[PATCH v2] conffile: clear invalid section on unmatched quote

From: xuchenchen <xuchenchen-UOlijcLmZ/[email protected]>

When a section header contains an opening quote without a matching
closing quote, conf_parse_line() leaves the newly allocated section
name active. As a result, assignments following the malformed header
can be added to that invalid section even though the diagnostic says
they will be ignored until the next section.

Free and clear the section name before returning so subsequent
assignments are ignored as intended.
