io_uring/kbuf: remove legacy kbuf caching
Commit 13ee854e7c04236a47a5beaacdcf51eb0bc7a8fa upstream.
Remove all struct io_buffer caches. It makes it a fair bit simpler.
Apart from from killing a bunch of lines and juggling between lists,
__io_put_kbuf_list() doesn't need ->completion_lock locking now.
