net/mlx5: fix verbs flow counter query

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")
