sched/core: Refactor the task_flags check for worker sleeping in sched_submit_work() 

JIRA: https://issues.redhat.com/browse/RHEL-25535

commit 3eafe225995c67f8c179011ec2d6e4c12b32a53d

    sched/core: Refactor the task_flags check for worker sleeping in sched_submit_work()

    Simplify the conditional logic for checking worker flags
    by splitting the original compound `if` statement into
    separate `if` and `else if` clauses.

    This modification not only retains the previous functionality,
    but also reduces a single `if` check, improving code clarity
    and potentially enhancing performance.
