Drivers: hv: util: move waiting for release to hv_utils_transport itself
BugLink: http://bugs.launchpad.net/bugs/1682561
Waiting for release_event in all three drivers introduced issues on release
as on_reset() hook is not always called. E.g. if the device was never
opened we will never get the completion.
Move the waiting code to hvutil_transport_destroy() and make sure it is
only called when the device is open. hvt->lock serialization should
guarantee the absence of races.
