mlxsw: Use the same maximum MTU value throughout the driver
Currently, the driver uses two different values for maximum MTU, one is stored in mlxsw_port->dev->max_mtu and the second is stored in mlxsw_port->max_mtu. The second one is set to value which is queried from firmware. This value was never tested, and unfortunately is not really supported. That means that with the existing code, user can set MTU to X, which is not really supported by firmware and which is bigger than buffer size which is allocated in pci. To make the driver consistent, use only mlxsw_port->dev->max_mtu for maximum MTU value, for buffers headroom add Ethernet frame headers, which are not included in mlxsw_port->dev->max_mtu. Remove mlxsw_port->max_mtu.
