Sam Li 7845e73147 block/io_uring: revert "Use io_uring_register_ring_fd() to skip fd operations" 
Resolves: https://gitlab.com/qemu-project/qemu/-/issues/1193

The commit "Use io_uring_register_ring_fd() to skip fd operations" broke
when booting a guest with iothread and io_uring. That is because the
io_uring_register_ring_fd() call is made from the main thread instead of
IOThread where io_uring_submit() is called. It can not be guaranteed
to register the ring fd in the correct thread or unregister the same ring
fd if the IOThread is disabled. This optimization is not critical so we
will revert previous commit.

This reverts commit e2848bc574
and 77e3f038af.
