Disable/Enable screenshot sound [1/2]

Change-Id: I9f32d0026833f9350a2e8e4bedaff3801f508e76
Remove unnecessary updateSurfaceScreenOn call.

This change stops updateSurfaceScreenOn() from being called one time
right after another. It's called at the end of stayAwake(boolean awake),
which is called right before updateSurfaceScreenOn() in release().
