SUNRPC: Fix a potential memory leak in rpc_new_client
If the call to rpciod_up() fails, we currently leak a reference to the struct rpc_xprt. As part of the fix, we also remove the redundant check for xprt!=NULL. This is already taken care of by the callers. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
