The legacy apis return a value of None on success, which was being converted to a value of 'nil' in the xmlrpc response.

The Xen IPI spec states that destroy, hard_shutdown, pause, resume, start, suspend, and unpause return void.  This patch makes it so and permits proper parsing of the response by clients (libxen) that follow the spec.
