[Crash-utility] [PATCH v3 1/3] s390x: Add non-zero vmalloc_start check to s390x_vr_IS_VMALLOC_ADDR()
Update s390x_vr_IS_VMALLOC_ADDR() to include a non-zero vmalloc_start
check, making it consistent with s390x_generic_IS_VMALLOC_ADDR().
Fixes: d0164e7e480a ("s390x: uncouple physical and virtual memory spaces")
