sshpeer: remove frivolous call to _cleanup()

_validaterepo() is called once during __init__. _cleanup()
no-ops if the self._pipe* attributes aren't set. These attributes
are set during _validaterepo(). So the call to _cleanup() isn't
necessary.

But just to be on the safe side, we add an assertion.
