powerpc: Don't ignore errors from set_memory_{n}p() in __kernel_map_pages()
set_memory_p() and set_memory_np() can fail.
As mentioned in linux/mm.h:
/*
* To support DEBUG_PAGEALLOC architecture must ensure that
* __kernel_map_pages() never fails
*/
So panic in case set_memory_p() or set_memory_np() fail
in __kernel_map_pages().
