Subject: [RFC ipsec-next] xfrm: make sha256 icv truncation length RFC-compliant

From: Lei Xu <Lei.Xu@...escale.com>

Currently the sha256 icv truncation length is set to 96bit
while the length is defined as 128bit in RFC4868.
This may result in somer errors when working with other IPsec devices
with the standard truncation length.
Thus, change the sha256 truncation length from 96bit to 128bit.
