net/mlx5: fix flow dump for modify field

[ upstream commit faecafc16f69c559323ec46ef110a771ce0bd7fb ]

When using other process to dump flow information, the modify field
information cannot be dumpped due to incorrect lcore value. Add loop
to get modify field information from all lcore to fix the issue.
