fix(qeth_rules): check the existence of /sys/devices/qeth/*/online beforehand 

On s390x KVM machines, the follow errors occurred,
    $ kdumpctl rebuild
    kdump: Rebuilding /boot/initramfs-4.18.0-321.el8.s390xkdump.img
    /usr/lib/dracut/modules.d/95qeth_rules/module-setup.sh: line 13: /sys/devices/qeth/*/online: No such file or directory
    /usr/lib/dracut/modules.d/95qeth_rules/module-setup.sh: line 13: /sys/devices/qeth/*/online: No such file or directory

because s390x KVM uses virtual devices and /sys/devices/qeth/*/online
doesn't exist. Eliminate this error by checking the existence
beforehand.
