ligd 2241969e5a SMP: fix crash when switch to new task which is still running 
cpu0 thread0:                        cpu1:
sched_yield()
nxsched_set_priority()
nxsched_running_setpriority()
nxsched_reprioritize_rtr()
nxsched_add_readytorun()
up_cpu_pause()
                                     IRQ enter
                                     arm64_pause_handler()
                                     enter_critical_section() begin
                                     up_cpu_paused() pick thread0
                                     arm64_restorestate() set thread0 tcb->xcp.regs to CURRENT_REGS
up_switch_context()
  thread0 -> thread1
arm64_syscall()
    case SYS_switch_context
     change thread0 tcb->xcp.regs
    restore_critical_section()
                                     enter_critical_section() done
                                     leave_critical_section()
                                     IRQ leave with restore CURRENT_REGS
                                     ERROR !!!

Reason:
As descript above, cpu0 swith task: thread0 -> thread1, and the
syscall() execute slowly, this time cpu1 pick thread0 to run at
up_cpu_paused(). Then cpu0 syscall execute, cpu1 IRQ leave error.

Resolve:
Move arm64_restorestate() after enter_critical_section() done

This is a continued fix with:
