Greg Kroah-Hartman 8c763a3cf5 Fix "net: ipv4: do not handle duplicate fragments as overlapping" ...

ade446403b ("net: ipv4: do not handle duplicate fragments as
overlapping") was backported to many stable trees, but it had a problem
that was "accidentally" fixed by the upstream commit 0ff89efb52 ("ip:
fail fast on IP defrag errors")

This is the fixup for that problem as we do not want the larger patch in
the older stable trees.
