From: Sriharsha Basavapatna <sriharsha.basavapa...@broadcom.com>
In some conditions when the driver fails to add a flow in HW and returns
an error back to the stack, the stack continues to invoke get_flow_stats()
and/or del_flow() on it. The driver fails these APIs with an error message
"no flow_node for cookie". The message gets logged repeatedly as long as
the stack keeps invoking these functions.
Fix this by removing the corresponding netdev_info() calls from these
functions.
Fixes: d7bc73053024 ("bnxt_en: add code to query TC flower offload stats")
