io_uring/poll: remove outdated comments of caching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.
Fixes: 13a99017ff19 ("io_uring: remove events caching atavisms")
