Subject: [PATCH] NFS: nfs41_walk_client_list(): re-lock before iterating

Sparse identified an execution path in nfs41_walk_client_list()
where the nfs_client_lock is not re-acquired before taking the next
loop iteration.

fs/nfs/nfs4client.c:437:9: sparse: context imbalance in
 'nfs41_walk_client_list' - different lock contexts for basic block
