dm: fix memory leak in dm_create_persistent() when starting metadata update thread fails
If, in dm_create_persistent(), the call to create_singlethread_workqueue()
fails then we'll return without freeing the memory allocated to 'ps', thus
leaking sizeof(struct pstore) bytes. This patch fixes the leak.
