io-wq: remove unused io_wqe_need_worker() function
A previous commit removed the need for this, but overlooked that we no longer use it at all. Get rid of it. Fixes: 685fe7feedb9 ("io-wq: eliminate the need for a manager thread") Reported-by: kernel test robot <lkp@intel.com> Signed-off-by: Jens Axboe <axboe@kernel.dk>
