net: hibmcge: fix the division by zero issue
When the network port is down, the queue is released, and ring->len is 0.
In debugfs, hbg_get_queue_used_num() will be called,
which may lead to a division by zero issue.
This patch adds a check, if ring->len is 0,
hbg_get_queue_used_num() directly returns 0.
Fixes: 40735e7543f9 ("net: hibmcge: Implement .ndo_start_xmit function")
