msm: pm-8x60: Add early return to msm_pm_enable_retention() If retention is already disabled, it is not necessary to send IPIs to the running CPUs to wake them up. Insert an early return for this scenario to reduce overhead during Krait rail voltage scaling, which calls this API on every voltage change.
