The error message is printed when the port cannot be used. Update the
error message to reflect that.

Isn't even the original condition (port >= max_ports) dead code? Why not
remove the condition altogether?

I also agree here if we can be sure, that .port_enable, .port_bridge_join and
.port_bridge_leave are only called for "valid" (<= max_ports) ports.
