Close the camera application immediately when media server dies.

Crash the app earlier. Otherwise, the app will crash later in other
places and the log is gone. Getting a new Camera object is not good
because it's hard for the app to reset the current state. For example,
the state can be autofocus, preview, snapshot, recording, saving
thumbnail.
