sunrpc: Add xprt after nfs4_test_session_trunk()
Multipathing: In case of NFSv3, rpc_clnt_test_and_add_xprt() adds the xprt to xprt switch (i.e. xps) if rpc_call_null_helper() returns success. But in case of NFSv4.1, it needs to do EXCHANGEID to verify the path along with check for session trunking. Add the xprt in nfs4_test_session_trunk() only when nfs4_detect_session_trunking() returns success. Also release refcount hold by rpc_clnt_setup_test_and_add_xprt().
