cpuidle, sched: Remove instrumentation from TIF_{POLLING_NRFLAG,NEED_RESCHED}

objtool pointed out that various idle-TIF management methods
have instrumentation:

Remove the instrumentation, because these methods are used in low-level
cpuidle code moving between states, that should not be instrumented.
