net/mlx5: fix verbs flow counter query
Checks
Commit Message
Function flow_verbs_counter_query() was recently modified.
The new 'if' condition uses a pointer to flow counter-set.
This pointer is valid only if flow contains a count action.
This patch adds check to verify the pointer is valid.
Fixes: d85c7b5ea59f ("net/mlx5: split hairpin flows")
