net/mlx5: fix flow engine type in function name
net/mlx5: fix flow engine type in function name

The concrete function names have a prefix for flow_dv.
This emphasizes the flow engine is Direct Verbs.

The function flow_get_aged_flows doesn’t have this prefix.
It creates an inconsistency with the other functions.

Update the function name to include dv.
