io_uring: run local task_work from ring exit IOPOLL reaping
In preparation for needing to shift NVMe passthrough to always use
task_work for polled IO completions, ensure that those are suitably
run at exit time. See commit:
9ce6c9875f3e ("nvme: always punt polled uring_cmd end_io work to task_work")
for details on why that is necessary.
