File 0118-95zfcp_rules-Enable-the-device-before-checking-devic.patch of Package dracut

Subject: 95zfcp_rules: Enable the device before checking device type

For creating dynamic udev rules parse-dasd.sh look for the device
type in sysfs, which of course does not exist if cio_ignore is
active. So first enable the device before checking.
