[PATCH] IB/hfi1: Avoid allocing memory on memoryless numa node

[Xianting Tian]

In architecture like powerpc, we can have cpus without any local memory
attached to it. In such cases the node does not have real memory.

Use local_memory_node(), which is guaranteed to have memory.
local_memory_node is a noop in other architectures that does not support
memoryless nodes.
