Eric Dumazet 5888f34249 ipv4: properly combine dev_base_seq and ipv4.dev_addr_genid 
[ Upstream commit 081a0e3b0d4c061419d3f4679dec9f68725b17e4 ]

net->dev_base_seq and ipv4.dev_addr_genid are monotonically increasing.

If we XOR their values, we could miss to detect if both values
were changed with the same amount.

Fixes: 0465277f6b3f ("ipv4: provide addr and netconf dump consistency info")
