net/mlx5e: HTB, Fix inconsistencies with QoS SQs number

[ Upstream commit 2f436f18 ]

When creating a new HTB class while the interface is down,
the variable that follows the number of QoS SQs (htb_max_qos_sqs)
may not be consistent with the number of HTB classes.

Previously, we compared these two values to ensure that
the node_qid is lower than the number of QoS SQs, and we
allocated stats for that SQ when they are equal.

Change the check to compare the node_qid with the current
number of leaf nodes and fix the checking conditions to
ensure allocation of stats_list and stats for each node.

Fixes: 214baf22
