[PATCH v3 6/8] block, bfq: remove redundant check in bfq_put_cooperator

From: Kemeng Shi
Date: Mon Jan 02 2023 - 20:55:13 EST


We have already avoided a circular list in bfq_setup_merge (see comments
in bfq_setup_merge() for details), so bfq_queue will not appear in it's
new_bfqq list. Just remove this check.
