virtcontainers: clh: Set the serial to NULL instead of OFF
The guest Linux kernel might try to access the serial port, and in case the serial is "off", this might cause some slowness because the port is not emulated at all. Problem is, when the port is not emulated, the default value when reading the I/O port will be 0, which has a special meaning in case of the serial port. It means there is some data ready to be read, which the kernel might try to read for some time, causing global system slowness. That's why it's safer to use "null" by default as this means the serial port will be emulated but anything written to it will be redirected to /dev/null.
