io_uring: unify task_work cancelation checks
Rather than do per-tw checking, which needs to dip into the task_struct
for checking flags, do it upfront before running task_work. This places
a 'cancel' member in io_tw_token_t, which is assigned before running
task_work for that given ctx.
This is both more efficient in doing it upfront rather than for every
task_work, and it means that io_should_terminate_tw() can be made
private in io_uring.c rather than need to be called by various
callbacks of task_work.
