Fix use-after-free in delayed link processing (newc format)

During archiving, if some of the "delayed" hard link entries
happened to disappear on filesystem (or become unreadable) for
some reason (most probably race), the old code free()d the 'entry'
and continued with the loop;  the next loop though dereferenced
'entry' and crashed the archiver.

Per report from Coverity.
