Trond Myklebust c688d2d8b0 SUNRPC: Prevent looping due to rpc_signal_task() races 
[ Upstream commit 5bbd6e863b15a85221e49b9bdb2d5d8f0bb91f3d ]

If rpc_signal_task() is called while a task is in an rpc_call_done()
callback function, and the latter calls rpc_restart_call(), the task can
end up looping due to the RPC_TASK_SIGNALLED flag being set without the
tk_rpc_status being set.
Removing the redundant mechanism for signalling the task fixes the
looping behaviour.
