dm snapshot persistent: fix missing cleanup in persistent_ctr error path ...
If an unsupported option is given then the early return from
persistent_ctr() leaked memory allocated for the 'pstore' and never
destroyed the 'metadata_wq'.
Fixes: b0d3cc011e53 ("dm snapshot: add new persistent store option to support overflow")
