x86: fix grub-bios-setup fail during sysupgrade

grub-bios-setup requires two images (boot.img and core.img), but they are missing. This make an error during sysupgrade: Upgrading bootloader on /dev/sda... grub-bios-setup: error: cannot open `/tmp/boot/boot/grub/boot.img': No such file or directory. Signed-off-by: 李国 <uxgood.org@gmail.com>

From: Pablo Neira Ayuso <pablo@netfilter.org> Date: Mon, 27 Nov 2017 21:55:14 +0100 Subject: [PATCH] netfilter: move checksum indirection to struct nf_ipv6_ops We cannot make a direct call to nf_ip6_checksum() because that would result in autoloading the 'ipv6' module because of symbol dependencies. Therefore, define checksum indirection in nf_ipv6_ops where this really belongs to. For IPv4, we can indeed make a direct function call, which is faster, given IPv4 is built-in in the networking code by default. Still, CONFIG_INET=n and CONFIG_NETFILTER=y is possible, so define empty inline stub for IPv4 in such case.
