[patch 15/24] s390: random values in result of BIODASDINFO2.

From: Horst Hummel <horst.hummel@de.ibm.com>

[patch 15/24] s390: random values in result of BIODASDINFO2.

Use kzalloc to get a zeroed buffer for the structure returned to
user space by the BIODASDINFO2 ioctl. Not all fields are set up,
e.g. the read_devno is missing.
