nfsd4: Fix forced-expiry locking
[ Upstream commit f7104cc1a9159cd0d3e8526cb638ae0301de4b61 ]
This should use the network-namespace-wide client_lock, not the
per-client cl_lock.
You shouldn't see any bugs unless you're actually using the
forced-expiry interface introduced by 89c905beccbb.
Fixes: 89c905beccbb "nfsd: allow forced expiration of NFSv4 clients"
