[PATCH] io_uring: kill stale comment for io_cqring_overflow_kill()

[Jens Axboe <axboe@kernel.dk>]

This function now deals only with discarding overflow entries on ring
free and exit, and it no longer returns whether we successfully flushed
all entries as there's no CQE posting involved anymore. Kill the
outdated comment.
