Summary
net: hibmcge: fix the division by zero issue
Details

In the Linux kernel, the following vulnerability has been resolved:

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, hbggetqueueusednum() will be called, which may lead to a division by zero issue.

This patch adds a check, if ring->len is 0, hbggetqueueusednum() directly returns 0.
