io_uring/poll: remove outdated comments of caching
Previous commit 13a99017ff19 ("io_uring: remove events caching atavisms") entirely removes the events caching optimization introduced by commit 81459350d581 ("io_uring: cache req->apoll->events in req->cflags"). Hence the related comment should also be removed to avoid misunderstanding.
