intel_idle: remove redundant local_irq_disable() call
irq disabling happens earlier in process_32.c:cpu_idle. Basically,
cpuidle_state->enter is called, cpu irq is disabled. cpuidle_state->enter
would turn on irq when exiting.
intel_idle doesn't follow this assumption. Although it doesn't cause real
issue, it misleads developers. Remove the call to local_irq_disable() at
entry.
