SUNRPC: xprt_autoclose() should not call xprt_disconnect()

The transport layer should do that itself whenever appropriate.

Note that the RDMA transport already assumes that it needs to call
xprt_disconnect in xprt_rdma_close().
For TCP sockets, we want to call xprt_disconnect() only after the
connection has been closed by both ends.
