osd: clear requeue_scrub_on_unblock flag after requeue scrub

We'd better clear requeue_scrub_on_unblock flag after successfully
requeuing scrub, this is for:
  1. if a newly initiated scrub is blocked by objectcontext again,
     reset requeue_scrub_on_unblock to true will be satisfied enough
     to meet such an appeal.
  2. so we don't push pg to the scrub queue when we don't want to
     by accident.
