io_uring: ensure io-wq context is always destroyed for tasks
If the task ends up doing no IO, the context list is empty and we don't
call into __io_uring_files_cancel() when the task exits. This can cause
a leak of the io-wq structures.
Ensure we always call __io_uring_files_cancel(), even if the task
context list is empty.
