    cpuidle, intel_idle: Fix CPUIDLE_FLAG_IRQ_ENABLE *again*

    So objtool found this bug:

      vmlinux.o: warning: objtool: intel_idle_irq+0x10c: call to trace_hardirqs_off() leaves .noinstr.text section

    As per commit 32d4fd57 ("cpuidle,intel_idle: Fix CPUIDLE_FLAG_IRQ_ENABLE"):

      "must not have tracing in idle functions"

    Clearly people can't read and tinker along until splat dissapears.
    This straight up reverts commit d295ad34 ("intel_idle: Fix false
    positive RCU splats due to incorrect hardirqs state").

    It doesn't re-introduce the problem because preceding patches fixed it
    properly.

    Fixes: d295ad34 ("intel_idle: Fix false positive RCU splats due to incorrect hardirqs state")
