This modification ensures that in scenarios where the buffer size is
insufficient for a zone report, the function will now properly set an
error status and proceed to a cleanup label, instead of merely
returning.
The following ASAN log reveals it:
==1767400==ERROR: LeakSanitizer: detected memory leaks
Direct leak of 312 byte(s) in 1 object(s) allocated from:
