net/mlx5e: psp: Remove unused PSP syndrome copy action

The PSP error flow table copies the HW syndrome to metadata register B,
but this value is never used in the RX path. Bad packets (auth fail,
bad trailer) are dropped by HW via explicit drop rules before reaching
software.

Remove the syndrome copy action, the syndrome macro, and the dead
syndrome check in the RX handler.
