io_uring: use system_unbound_wq for ring exit work

Browse source

We currently use system_wq, which is unbounded in terms of number of
workers. This means that if we're exiting tons of rings at the same
time, then we'll briefly spawn tons of event kworkers just for a very
short blocking time as the rings exit.

Use system_unbound_wq instead, which has a sane cap on the concurrency
level.
