  - net/mlx5: fs, fix UAF in flow counter release Fix a kernel trace [1] caused by releasing an HWS action of     a local flow counter in mlx5_cmd_hws_delete_fte(), where the HWS action refcount and mutex were not     initialized and the counter struct could already be freed when deleting the rule. Fix it by adding the     missing initializations and adding refcount for the local flow counter struct. [1] Kernel log: Call Trace:
