memblock: replace __alloc_bootmem_node_nopanic with memblock_alloc_tr…

…y_nid_nopanic

The __alloc_bootmem_node_nopanic() attempts to allocate memory for a
specified node. If the allocation fails it then retries to allocate memory
from any node. Upon success, the allocated memory is set to 0.

The memblock_alloc_try_nid_nopanic() does exactly the same thing and can be
used instead.
