Christophe Leroy 9cbacb834b 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().
