sunrpc: Use rcu_barrier() on unload.
The sunrpc module uses rcu_call() thus it should use rcu_barrier() on
module unload.
Have not verified that the possibility for new call_rcu() callbacks
has been disabled. As a hint for checking, the functions calling
call_rcu() (unx_destroy_cred and generic_destroy_cred) are
registered as crdestroy function pointer in struct rpc_credops.
