Re: [PATCH v4 net] octeontx2-pf: reset HTB scheduler topology before freeing queues

HTB offload programs NIX_AF_TLxX_TOPOLOGY on QoS-allocated scheduler
queues via otx2_qos_txschq_set_parent_topology(), but teardown freed
those queues without clearing TOPOLOGY.  The AF only restores PARENT and
SCHEDULE on free, so PRIO_ANCHOR/RR_PRIO settings can survive in the
shared scheduler pool and affect later allocations.

Add otx2_qos_reset_schq_topology() and otx2_qos_free_hw_schq() to zero
TL4 through TL2 TOPOLOGY before each schq is returned to the AF during
hierarchy teardown and cfg rollback.  Skip the aggregation level (TL1):
it is a per-tx-link queue shared by the PF, default Tx hierarchy and VFs,
and is not freed back to the AF by nix_txschq_free_one().
