Subject: block: kyber: fix domain token leak during requeue

From: Ming Lei <[email protected]>

commit ba989a01469d027861e55c8f1121edadef757797 upstream.

When requeuing request, the domain token should have been freed before re-inserting the request to io scheduler. Otherwise, the assigned domain token will be leaked, and IO hang can be caused.
