s390/monwriter: do not use stack buffers for hardware data
With CONFIG_VMAP_STACK=y the stack is allocated from the vmalloc space.
Data structures passed to a hardware or a hypervisor interface that
requires V=R can not be allocated on the stack anymore.
Use kmalloc to get memory for the appldata_parameter_list and
appldata_product_id structures.
