mm: numa_memblks: remove redundant numa_nodemask_from_meminfo()

Browse Source 
numa_add_memblk() now sets each added node in numa_nodes_parsed, so
numa_nodes_parsed already contains every node that owns memory.  The nodes
numa_nodemask_from_meminfo() adds from numa_meminfo are already set, so the
calls in numa_alloc_distance() and numa_register_meminfo() are redundant.

So remove both call sites and the unused function itself.

No functional change.
