[S390] dasd: Add sysfs attribute status and generate uevents.
This patch adds a sysfs-attribute 'status' to make the DASD device-status accessible from user-space. In addition, the DASD driver generates an uevent(CHANGE) for the ccw-device on each device-status change. This enables user-space applications (e.g. udev) to do related processing.
