ipsec: one thread index per-SA
Type: improvement AN SA is uni-drectional therefore it can be used only for encrypt or decrypt, not both. So it only needs one thread ID. free up some space on the 1st cacheline. Signed-off-by: Neale Ranns <neale@graphiant.com> Change-Id: I21cb7cff70a763cbe2bffead860b574bc80b3136
