Pawel Dziepak b258298c70 kernel: Protect cpu_ent::active_time with sequential lock
atomic_{get, set}64() are problematic on architectures without 64 bit
compare and swap.
Also, using sequential lock instead of atomic access ensures that
any reads from cpu_ent::active_time won't require any writes to shared
memory.
