[IPV4]: Swap the ifa allocation with the"ipv4_devconf_setall" call
According to Herbert, the ipv4_devconf_setall should be called only when the ifa is added to the device. However, failed ifa allocation may bring things into inconsistent state. Move the call to ipv4_devconf_setall after the ifa allocation. Fits both net-2.6 (with offsets) and net-2.6.25 (cleanly). Signed-off-by: Pavel Emelyanov <xemul@openvz.org> Signed-off-by: David S.
