> Convert SFQ to use the new qdisc-specific drop reason infrastructure.

> This patch demonstrates how to convert a flow-based qdisc to use the
> new enum qdisc_drop_reason. As part of this conversion:
>
> - Add QDISC_DROP_MAXFLOWS for flow table exhaustion
> - Rename FQ_FLOW_LIMIT to generic FLOW_LIMIT, now shared by FQ and SFQ
> - Use QDISC_DROP_OVERLIMIT for sfq_drop() when overall limit exceeded
> - Use QDISC_DROP_FLOW_LIMIT for per-flow depth limit exceeded
>
> The FLOW_LIMIT reason is now a common drop reason for per-flow limits,
> applicable to both FQ and SFQ qdiscs.
