io_uring: don't save/restore iowait state
This kind of state is per-syscall, and since we're doing the waiting off
entering the io_uring_enter(2) syscall, there's no way that iowait can
already be set for this case. Simplify it by setting it if we need to,
and always clearing it to 0 when done.
Fixes: 7b72d661f1f2 ("io_uring: gate iowait schedule on having pending requests")
