ligd 1fb4f8f50e arch: change nxsched_suspend/resume_scheduler() called position 
for the citimon stats:

thread 0:                     thread 1:
enter_critical (t0)
up_switch_context
note suspend thread0 (t1)

                              thread running
                              IRQ happen, in ISR:
                                post thread0
                                up_switch_context
                                note resume thread0 (t2)
                                ISR continue f1
                                ISR continue f2
                                ...
                                ISR continue fn

leave_critical (t3)

You will see, the thread 0, critical_section time is:
(t1 - t0) + (t3 - t2)

BUT, this result contains f1 f2 .. fn time spent, it is wrong
to tell user thead0 hold the critical lots of time but actually
not belong to it.

Resolve:
change the nxsched_suspend/resume_scheduler to real hanppends
