io_uring/io-wq: fix incorrect io_wq_for_each_worker() termination logic
commit e0392a10c9e80a3991855a81317da3039fcbe32c upstream.
A previous commit added this helper, and had it terminate if false is
returned from the handler. However, that is completely opposite, it
should abort the loop if true is returned.
Fix this up by having io_wq_for_each_worker() keep iterating as long
as false is returned, and only abort if true is returned.
