Hugepages can be specified to pernode since "hugetlbfs: extend the
definition of hugepages parameter to support node allocation", but the
following problem is observed.

Confusing behavior is observed when both 1G and 2M hugepage is set
after "numa=off".
 cmdline hugepage settings:
  hugepagesz=1G hugepages=0:3,1:3
  hugepagesz=2M hugepages=0:1024,1:1024
 results:
  HugeTLB registered 1.00 GiB page size, pre-allocated 0 pages
  HugeTLB registered 2.00 MiB page size, pre-allocated 1024 pages

Furthermore, confusing behavior can be also observed when an invalid node
behind a valid node.  To fix this, never allocate any typical hugepage
when an invalid parameter is received.
