[PATCH 3/5] io-wq: use __set_notify_signal() to wake workers

[Jens Axboe <axboe@kernel.dk>]

The only difference between set_notify_signal() and __set_notify_signal()
is that the former checks if it needs to deliver an IPI to force a
reschedule. As the io-wq workers never leave the kernel, and IPI is never
needed, they simply need a wakeup.
