msm8226-common: CMActions: Hold a wakelock when the screen is on

Sometimes the device is suspended before ACTION_SCREEN_OFF is received.
When this happens, the proximity sensor doesn't get enabled, breaking
the wake gesture. Hold a wakelock when the screen is on and release it
only once the sensor has been enabled.
