Dave Sparks 2133640028 Retry overlay create if it fails. Bug 2153980. ...

Occasionally we see references to the overlay hanging around long
enough to cause problems in applications when they tried to destroy
the overlay and re-create it. This patch causes the camera HAL to
retry the overlay creation call if it fails every 20ms up to 50
times before it gives up.
