nfsd: make ownerstr_hashtbl allocated per net

This hash holds open owner 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.
