Commit c77e22834ae9 ("NFSv4: Fix a potential sleep while atomic in nfs4_do_reclaim()") separate out the freeing of the state owners from nfs4_purge_state_owners() and finish it outside the rcu lock. However, the error path is omitted. As a result, the state owners in "freeme" will not be released. Fix it by adding freeing in the error path.
