MIPS: smp-cmp: Use right include for task_struct

When task_struct was moved, this MIPS code was neglected. Evidently
nobody is using it anymore. This fixes this build error:

                 from ./include/linux/thread_info.h:37,

                 from ./include/linux/sched.h:11,
                 from arch/mips/kernel/smp-cmp.c:22:
