block: Always initialize bio IO priority on submit
Currently, IO priority set in task's IO context is not reflected in the bio->bi_ioprio for most IO (only io_uring and direct IO set it). This results in odd results where process is submitting some bios with one priority and other bios with a different (unset) priority and due to differing priorities bios cannot be merged. Make sure bio->bi_ioprio is always set on bio submission.
