Kinjal Bhavsar 7c05f8ce9d display: Fix Overlay state transitions 
Trigger overlay state change for S3D format changes.

Close both overlay channels only when transition to/from 3D display
happen.

The closeChannel resets the Overlay state variables. Any changes to
the state variables prior to closechannel are lost. Update state
variables after calling closeChannel.

Remove unused variables.
