x86-64, NUMA: consolidate and improve memblk sanity checks

memblk sanity check was scattered around and incomplete.  Consolidate
and improve.

* Confliction detection and cutoff_node() logic are moved to
  numa_cleanup_meminfo().

* numa_cleanup_meminfo() clears the unused memblks before returning.

* Check and warn about invalid input parameters in numa_add_memblk().

* Check the maximum number of memblk isn't exceeded in
  numa_add_memblk().

* numa_cleanup_meminfo() is now called before numa_emulation() so that
  the emulation code also uses the cleaned up version.
