Subject: hugetlb: add generic definition of NUMA_NO_NODE

Move definition of NUMA_NO_NODE from ia64 and x86_64 arch specific headers
to generic header 'linux/numa.h' for use in generic code.  NUMA_NO_NODE
replaces bare '-1' where it's used in this series to indicate "no node id
specified".  Ultimately, it can be used to replace the -1 elsewhere where
it is used similarly.
