[PATCH] io-wq: ensure work->task_pid is cleared on init

[Jens Axboe <axboe@xxxxxxxxx>]

We use ->task_pid for exit cancellation, but we need to ensure it's
cleared to zero for io_req_work_grab_env() to do the right thing.

Fixes: 36282881a795 ("io-wq: add io_wq_cancel_pid() to cancel based on a specific pid")
