wakelock: acquire lock during whole ringtone and start process

some buggy devices would enter sleep/power saving mode while screen is
turned of by proximity sensor. it may cause unexpected disconnection
when user using earpiece to talk.

so there is no need to acquire/release on every manualTurnScreen On/Off
