Yu Kuai 7f77f3dab5 block, bfq: fix uaf for bfqq in bic_set_bfqq() ... [ Upstream commit b600de2d7d ] After commit 64dc8c732f ("block, bfq: fix possible uaf for 'bfqq->bic'"), bic->bfqq will be accessed in bic_set_bfqq(), however, in some context bic->bfqq will be freed, and bic_set_bfqq() is called with the freed bic->bfqq. Fix the problem by always freeing bfqq after bic_set_bfqq().
