[PATCH 2/2] SUNRPC: Ensure call_connect_status() deals correctly with SOFTCONN tasks

[Stefan Bader]

From: Steve Dickson <steved at redhat.com>

Don't schedule an rpc_delay before checking to see if the task
is a SOFTCONN because the tk_callback from the delay (__rpc_atrun)
clears the task status before the rpc_exit_task can be run.
