SUNRPC: Move xprt_update_rtt callsite
Since commit 33849792cbcd ("xprtrdma: Detect unreachable NFS/RDMA servers more reliably"), the xprtrdma transport now has a ->timer callout. But xprtrdma does not need to compute RTT data, only UDP needs that. Move the xprt_update_rtt call into the UDP transport implementation.
