In the Linux kernel, the following vulnerability has been resolved:
nfsd: under NFSv4.1, fix double svc_xprt_put on rpc_create failure
On error situation `clp->cl_cb_conn.cb_xprt` should not be given
a reference to the xprt otherwise both client cleanup and the
error handling path of the caller call to put it. Better to
delay handing over the reference to a later branch.
