msm: cpuidle: Don't disable irqs again

            cpu_idle() disables irqs before calling down into the cpuidle
            driver via cpuidle_idle_call(). Disabling irqs again in
            msm_cpuidle_enter() is wasteful and unnecessary. It also inhibits
            our ability to determine the largest irq latency when the cpu
            idles for extended periods of time because the irqsoff trace is
            reenabled when the irqs are disabled in msm_cpuidle_enter().

            Note that we still reenable irqs before returning, as is required
            by the ARM idle loop.
