This hash holds established sessions state and closely associated with
nfs4_clients info, which are network namespace aware. So let's make it
allocated per network namespace too.
Note: this hash can be allocated in per-net operations. But it looks
better to allocate it on nfsd state start and thus don't waste resources
if server is not running.

as a parameter and thus loop over all networks was replaced by only one call
for ip map cache purge.

Otherwise, we get a warning or error similar to this when building with
CONFIG_NFSD_V4 disabled:
ERROR: "nfsd4_cld_block" [fs/nfsd/nfsd.ko] undefined!
Fix this by wrapping the calls to rpc_pipefs_notifier_register and
..._unregister in another function and providing no-op replacements
when CONFIG_NFSD_V4 is disabled.

In the event that rpc_pipefs isn't mounted when nfsd starts, we
must register a notifier to handle creating the dentry once it
is mounted, and to remove the dentry on unmount.

Eventually, we'll need this when nfsd gets containerized fully. For
now, create a struct on a per-net-namespace basis that will just hold
a pointer to the cld_net structure. That struct will hold all of the
per-net data that we need for the cld tracker.
Eventually we can add other pernet objects to struct nfsd_net.
