[PATCH 2/4] nodedev: improve DASD detection

In newer DASD driver versions the ID_TYPE tag is supported. This tag is missing after a system reboot but when the ccw device is set offline and online the tag is included. To fix this version independently we need to check if devices detected as type disk is actually a DASD to maintain the node object consistency and not end up with multiple node objects for DASDs.
