[PATCH v2] [net] net: airoha: Fix QoS counter configuration for Tx-fwd channels

[Wayen Yan]

In airoha_qdma_init_qos_stats(), the Tx-fwd counter was incorrectly
using register index (i << 1) instead of ((i << 1) + 1). This caused
the Tx-fwd configuration to overwrite the Tx-cpu configuration for
each QoS channel, resulting in incorrect QoS statistics.

Fix by using the correct register index ((i << 1) + 1) for Tx-fwd
counter configuration.
