ip route: restore_handler should check tb[RTA_PREFSRC] for local networks
Prior to this patch, If one route entry's RTA_PREFSRC and RTA_GATEWAY
both were NULL, it was supposed to be restored ONLY as a local address.
But as it didn't check tb[RTA_PREFSRC] when restoring local networks,
rtattr_cmp would return a success if it was NULL, this route entry would
be restored again as a local network.
This patch is to add tb[RTA_PREFSRC] check when restoring local networks.
