kernel: Fix hanging os:cmd race condition
If the port terminates before Port ! close is issued,
there will be no 'closed' reply, so the old code would
hang. As it turns out there is no way to figure out
if a closed reply is supposed to come as that reply
is sent after all links and monitors are triggered.
So we have to use the synchronous port_close to close
the port.
