NFS: Allow walking nfs_client.cl_superblocks list outside client.c
We're about to move some fields from struct nfs_client to struct
nfs_server. There is a many-to-one relationship between nfs_servers
and nfs_clients. After these fields are moved to the nfs_server
struct, to visit all of the data in these fields that is owned by one
nfs_client, code will need to visit each nfs_server on the
cl_superblocks list for that nfs_client.
To serialize changes to the cl_superblocks list during these little
expeditions, protect the list with RCU.
