SMP: Introduce spin_lock_wo_note() and spin_unlock_wo_note()

These APIs are used in sched_note.c to protect instumentation data.
The deffrence between these APIs to exsiting spin_lock() and spin_unlock()
is that they do not perform insturumentation to avoid recursive call
when SCHED_INSTRUMENTATION_SPINLOCKS=y.

+ * Input Parameters:
