[IPSEC] flow: reorder "struct flow_cache_entry" and remove SLAB_HWCACHE_ALIGN
1) We can shrink sizeof(struct flow_cache_entry) by 8 bytes on 64bit arches. 2) No need to align these structures to hardware cache lines, this only waste ram for very litle gain. Signed-off-by: Eric Dumazet <dada1@cosmosbay.com> Signed-off-by: David S. Miller <davem@davemloft.net>
