io_uring: kill sqo_dead and sqo submission halting

As SQPOLL task doesn't poke into ->sqo_task anymore, there is no need to
kill the sqo when the master task exits. Before it was necessary to
avoid races accessing sqo_task->files with removing them.

[axboe: don't forget to enable SQPOLL before exit, if started disabled]
