watchdog: diag288_wdt: do not use stack buffers for hardware data
commit fe8973a3ad0905cb9ba2d42db42ed51de14737df upstream.
With CONFIG_VMAP_STACK=y the stack is allocated from the vmalloc space.
Data passed to a hardware or a hypervisor interface that
requires V=R can no longer be allocated on the stack.
Use kmalloc() to get memory for a diag288 command.
