parisc: fix GFP_KERNEL use while atomic in unwinder
Since unwind_frame_init_from_blocked_task() may be called from
interrupt/in_atomic context, it needs to kmalloc() memory with
GFP_ATOMIC instead of GFP_KERNEL.
This fixes this warning (ShowTasks called from sysrq handler):
BUG: sleeping function called from invalid context at mm/slab.c:3044
in_atomic(): 1, irqs_disabled(): 1, pid: 2119, name: miniruby
