Mikhail Zaslonko d8f504f271 zdump/dfi: Fix vm_info_get() check for non-VR kernel ...

Since the following kernel commit:
"32db401965f1 s390/mm: Pin identity mapping base to zero"
we can have zero identity_base value in os_info. This makes zgetdump
check for non-VR kernel in vm_info_get() incorrect what leads to missing
data (e.g. UTS kernel version) in 'zgetdump -i' output.
Check for zero kaslr_offset value instead (like crash and makedumpfile
do) in order to identify non-VR kernel.
