Mike Marciniszyn de427b662b IB/hfi1: Fix probe time panic when AIP is enabled with a buggy BIOS 
commit 5de61a47eb9064cbbc5f3360d639e8e34a690a54 upstream.

A panic can result when AIP is enabled:

The issue happens when pcibus_to_node() returns NO_NUMA_NODE.

Fix this issue by moving the initialization of dd->node to hfi1_devdata
allocation and remove the other pcibus_to_node() calls in the probe path
and use dd->node instead.

Affinity logic is adjusted to use a new field dd->affinity_entry as a
guard instead of dd->node.
