Xen devel - Nov 2013 - [PATCH 1/1] xen-netback: include definition of csum_ipv6_magic

We are now using csum_ipv6_magic, include the appropriate header.
Avoids the following error:

    drivers/net/xen-netback/netback.c:1313:4: error: implicit declaration of
function ''csum_ipv6_magic''
[-Werror=implicit-function-declaration]
        tcph->check = ~csum_ipv6_magic(&ipv6h->saddr,

    Found while trying to couple latest kernels for arm64 platforms.
    Looks like it got missed in the transition.
