nodedev: improve DASD detection

Browse Source 
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.
