SUNRPC: Eliminate task->tk_xprt accesses that bypass rcu_dereference()
tk_xprt is just a shortcut for tk_client->cl_xprt, however cl_xprt is defined as an __rcu variable. Replace dereferences of tk_xprt with non-rcu dereferences where it is safe to do so. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
