svcrdma: do not unregister device for listeners
On an rdma-capable machine, a start/stop/start and then on a stop of
a knfsd server would lead kref underflow warning because svc_rdma_free
would indiscriminately unregister the rdma device but a listening
transport never calls the rdma_rn_register() thus leading to kref
going down to 0 on the 1st stop of the server and on the 2nd stop
it leads to a problem.
