mm: replace all open encodings for NUMA_NO_NODE

Patch series "Replace all open encodings for NUMA_NO_NODE", v3.

All these places for replacement were found by running the following grep
patterns on the entire kernel code. Please let me know if this might have
missed some instances. This might also have replaced some false positives.
I will appreciate suggestions, inputs and review.

1. git grep "nid == -1"
2. git grep "node == -1"
3. git grep "nid = -1"
4. git grep "node = -1"

This patch (of 2):

At present there are multiple places where invalid node number is encoded
as -1.  Even though implicitly understood it is always better to have
macros in there.  Replace these open encodings for an invalid node number
with the global macro NUMA_NO_NODE.  This helps remove NUMA related
assumptions like 'invalid node' from various places redirecting them to a
common definition.
