Subject: [PATCH] cache: Call vm.Disconnect() when close vm

After previous commit, found that kata-proxy is not quit
when vmcache server is stopped by ctrl-c.
The cause is current kata-proxy is setsid when it exec.  It will
not get the signal ctrl-c.

Call vm.Disconnect() when close vm in cache factory to handle
this issue.

Fixes: #1726
