Commit 88e6c42e40de ("io_uring/io-wq: add check free worker before create new worker") reused the variable `do_create` for something else, abusing it for the free worker check.

This caused the value to effectively always be `true` at the time `nr_workers < max_workers` was checked, but it should really be `false`. This means the `max_workers` setting was ignored, and worse: if the limit had already been reached, incrementing `nr_workers` was skipped even though another worker would be created.
