Vitaly Kuznetsov a524bb57dd Drivers: hv: util: move waiting for release to hv_utils_transport itself 
[ Upstream commit e9c18ae6eb ]

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.

Fixes: 5a66fecbf6 ("Drivers: hv: util: kvp: Fix a rescind processing issue")
Fixes: 20951c7535 ("Drivers: hv: util: Fcopy: Fix a rescind processing issue")
Fixes: d77044d142 ("Drivers: hv: util: Backup: Fix a rescind processing issue")
