Fix LVM thin pool creation race

In the event that two copied of the LVM driver get init called at
the same time (e.g. cinder-volume and cinder-backup getting
started in parallel, on the same host), it is possible for the
thin pool check/create to race. Add a simple recheck if the create
fails, to cover this window.
