Don't wait for the MountService to be ready when encrypting

The MountService will take 2 minutes to time out trying to
get volume and asec lists from vold, because vold is busy encrypting
and not listening to requests on its socket.  So when encrypting,
do not wait for it to be ready, as we don't have /data mounted anyhow.
