NFSv4: keep state manager thread active if swap is enabled
If we are swapping over NFSv4, we may not be able to allocate memory to
start the state-manager thread at the time when we need it.
So keep it always running when swap is enabled, and just signal it to
start.
This requires updating and testing the cl_swapper count on the root
rpc_clnt after following all ->cl_parent links.
