i40e: Fix add TC filter for IPv6
[ Upstream commit 61c1e0eb8375def7c891bfe857bb795a57090526 ]
Fix insufficient distinction between IPv4 and IPv6 addresses
when creating a filter.
IPv4 and IPv6 are kept in the same memory area. If IPv6 is added,
then it's caught by IPv4 check, which leads to err -95.
