ipv4: keep skb->dst around in presence of IP options

Upstream commit 34b2cef20f19c87999fff3da4071e66937db9644
("ipv4: keep skb->dst around in presence of IP options") incorrectly
root caused commit d826eb14ecef ("ipv4: PKTINFO doesnt need dst
reference") as bug origin.

This patch should fix the issue for 3.2.xx stable kernels, since IPv4
options seem to get more traction these days, after years of oblivion ;)

Fixes: f84af32cbca70 ("net: ip_queue_rcv_skb() helper"))
