stubdom: fix a race that affects live migration with stubdoms
This patch fixes a race during live migration with stubdoms: right
after the stubdom dies the configuration file of the VM is removed by
stubdom-dm but, in case of a live migration, the configuration file
could be the one of the new VM in the process of being created.
Removing the config file before destroying the stubdom is enough to
solve the race.
