mesos git commit: Avoid duplicate unmount dangling mount point.

Avoid duplicate unmount dangling mount point.

We could potentially schedule the framework dir, executor dir, and
executor run sandbox to gc at the same time, and then these
paths will be gc independently, although they are parents and
children directories. This patch makes sure we do not call unmount
anymore after a success.
