From: Kalesh AP <kalesh-anakkur.pura...@broadcom.com>
For the stingray platform and other platforms needing tighter
control of resource utilization, we process async events on
receive completion ring0.
For other chips there is a dedicated completion ring for
asynchronous event handling instead of handling these events
on a receive completion ring.
This patch fixes the check for rxq0 stop.
Fixes: 05b5e4821c1e ("net/bnxt: use dedicated CPR for async events")
