net-sysfs: restore behavior for not running devices
modprobe dummy dumdummies=1
Old behavior :
$ cat /sys/class/net/dummy0/carrier
cat: /sys/class/net/dummy0/carrier: Invalid argument
After blamed commit, an empty string is reported.
$ cat /sys/class/net/dummy0/carrier
$
In this commit, I restore the old behavior for carrier,
speed and duplex attributes.
