protocol/server: Include a check to validate xprt->client
rpc_transport entries(xprt) are added to the conf->xprt_list
during client connection with the server. But the client object is created
and assigned to that transport object only during GF_HANDSK_SETVOLUME. Hence
till that period, there could be xprt entries in the xprt_list without client
associated with it. Added a check to validate the client object during upcall
notify.
