netfilter: conntrack: use siphash_4u64
This function is used for every packet, siphash_4u64 is noticeably faster
than using local buffer + siphash:
Before:
1.23% kpktgend_0 [kernel.vmlinux] [k] __siphash_unaligned
0.14% kpktgend_0 [nf_conntrack] [k] hash_conntrack_raw
After:
0.79% kpktgend_0 [kernel.vmlinux] [k] siphash_4u64
0.15% kpktgend_0 [nf_conntrack] [k] hash_conntrack_raw
In the pktgen test this gives about ~2.4% performance improvement.
