net/mlxfw: Verify FSM error code translation doesn't exceed array size
Array mlxfw_fsm_state_err_str contains value to string translation, when
values are provided by mlxfw_dev. If value is larger than
MLXFW_FSM_STATE_ERR_MAX, return "unknown error" as expected instead of
reading an address than exceed array size.
Fixes: 410ed13cae39 ("Add the mlxfw module for Mellanox firmware flash process")
