kernel - Fix startup race in usched_dfly

* Use a master configuration lock for usched_dfly's thread
  creation, ensuring that no thread tries to check dfly_pcpu[]
  until the whole thing has been initialized.

* Fixes occassional panic in usched_dfly on boot on many-cores
  systems due to a lower-numbered usched thread triggering before
  dfly_pcpu is completely initialized.
