[Ovidiu Panait]

This fixes a race conditition which leaves devices mounted, causing the
following anaconda installation failure:
File "/usr/lib64/python3.5/site-packages/gi/overrides/BlockDev.py", line 963, in wrapped
  raise transform[1](msg)
File "/usr/lib64/python3.5/site-packages/blivet/devices/lvm.py", line 913, in _teardown
  blockdev.lvm.lvdeactivate(self.vg.name, self._name)
File "/usr/lib64/python3.5/site-packages/blivet/threads.py", line 53, in run_with_lock
  return m(*args, **kwargs)
File "/usr/lib64/python3.5/site-packages/blivet/devices/storage.py", line 431, in teardown
  self._teardown(recursive=recursive)
File "/usr/lib64/python3.5/site-packages/blivet/threads.py", line 53, in run_with_lock
  return m(*args, **kwargs)
File "/usr/lib64/python3.5/site-packages/blivet/devices/lvm.py", line 1933, in teardown
  return DMDevice.teardown(self, recursive)
gi.overrides.BlockDev.LVMError: Process reported exit code 5:   Logical volume wrll_intel-x86-64/root contains a filesystem in use.
