Endpoint.sbLeave: don't load ep from store

Browse Source 
Because it loaded the Endpoint object from store and operated
on that copy rather than its own receiver, sbJoin couldn't
successfully roll back on error if the Endpoint was not included
in the Sandbox's list of endpoints, or its current state had
not been written to store after the error occurred.

So, for example, releaseOSSboxResources() would not be called
to delete interfaces created in the container's netns.
