Remove the check of data->free_work and data->do_work in io_wq_create
io_wq_create is only called in io_init_wq_offload, which has already
initialized free_work and do_work to io_wq_free_work and io_wq_submit_work
respectively, so there is no need to detect whether free_work and
do_work are null pointers in io_wq_create.
