ipv4: use RCU protection in ip_dst_mtu_maybe_forward()
[ Upstream commit 071d8012869b6af352acca346ade13e7be90a49f ]
ip_dst_mtu_maybe_forward() must use RCU protection to make
sure the net structure it reads does not disappear.
Fixes: f87c10a8aa1e8 ("ipv4: introduce ip_dst_mtu_maybe_forward and protect forwarding path against pmtu spoofing")
