[PATCH linux] netfilter: Remove unnecessary ret assignment

[cgel . zte]

From: luo penghao <luo.penghao@xxxxxxxxxx>

Regardless of whether the subsequent (copy_to_user(user, &info, *len) != 0)
holds, the value of ret will be assigned a new value.

The clang_analyzer complains as follows:

net/ipv6/netfilter/ip6_tables.c:

Value stored to 'ret' is never read
