Only use-case here are pad mode LEDs that now live in /sys/class/leds. Asking
the server to open them is pointless, the server only knows how to open Option
"Device". And since the LEDs are in sysfs we should have access to them
anyway, so no need for jumping through or hula-ing hoops.
xf86CloseSerial() works as intended as it's a slim wrapper around close(), so
we only have to worry about the open() path here.
