net: sched: rename QDISC_DROP_FQ_* to generic names
Rename FQ-specific drop reasons to generic names:
- QDISC_DROP_FQ_BAND_LIMIT -> QDISC_DROP_BAND_LIMIT
- QDISC_DROP_FQ_HORIZON_LIMIT -> QDISC_DROP_HORIZON_LIMIT
This follows the principle that drop reasons should describe the drop
mechanism rather than being tied to a specific qdisc implementation.
These concepts (priority band limits, timestamp horizon) could apply
to other qdiscs as well.
Remove the local macro define FQDR() and instead use the
full QDISC_DROP_* name to make it easier to navigate code.
