Fixes for MMS setparameter crashes

1. Fix native crash for set parameter when
   zoom is applied in MMS mode and while
   recording is in progress.
2. Don't allow restart of preview or preview
   stop when recording is in progress.
3. Fix slow zoom when in MMS mode casued by
   unnecessary preview restarts.
4. Fix initial jerky preview when you start
   recording in MMS mode caused by having
   to restart preview.
