[PATCH net-next nfs 1/6] net: Convert rpcsec_gss_net_ops

[Kirill Tkhai <ktkhai@virtuozzo.com>]

These pernet_operations initialize and destroy sunrpc_net_id
refered per-net items. Only used global list is cache_list,
and accesses already serialized.

sunrpc_destroy_cache_detail() check for list_empty() without
cache_list_lock, but when it's called from unregister_pernet_subsys(),
there can't be callers in parallel, so we won't miss list_empty()
in this case.
