commit a144ea4b7a13087081ab5402fa9ad0bcfd249e67 [IPV4]: annotate struct in_ifaddr

Missed this extra byteswap as the isdn inlines hide the htonl inside put_u32
which causes an extra byteswap on little-endian arches.

Dave, this is the minimal patch suitable to fix mainline without any net-next
material mixed in.  I'd suggest sending this one to Linus and then applying
my previous patch to net-next (if you need a resend, just ask)

Then whenever you do your net-next merge with Linus, the resolution should be trivial.

Please resend when I do my merges after Linus takes the change, I'll announce this
on netdev as I always do.
