kthread: add kthread_stop_put
[ Upstream commit 6309727ef27162deabd5c095c11af24970fba5a2 ]
Add a kthread_stop_put() helper that stops a thread and puts its task
struct. Use it to replace the various instances of kthread_stop()
followed by put_task_struct().
Remove the kthread_stop_put() macro in usbip that is similar but doesn't
return the result of kthread_stop().
