Nilay Shroff e3ef9445cd block: validate QoS before calling __rq_qos_done_bio() ... If a bio has BIO_QOS_xxx set, it doesn't guarantee that q->rq_qos is also present at-least for stacked block devices. For instance, in case of NVMe when multipath is enabled, the bottom device may have QoS enabled but top device doesn't. So always validate QoS is enabled and q->rq_qos is present before calling __rq_qos_done_bio().
