mm: fix NUMA accounting in numastat.txt

In Documentation/numastat.txt, it confused me.  For example, there are
nodes [0,1] in system.

barrios:~$ cat /proc/zoneinfo | egrep 'numa|zone'
Node 0, zone	DMA
	numa_hit	33226
	numa_miss	1739
	numa_foreign	27978
	..
	..
Node 1, zone	DMA
	numa_hit	307
	numa_miss	46900
	numa_foreign	0

1) In node 0,  NUMA_MISS means it wanted to allocate page
in node 1 but ended up with page in node 0

2) In node 0, NUMA_FOREIGN means it wanted to allocate page
in node 0 but ended up with page from Node 1.

But now, numastat explains it oppositely about (MISS, FOREIGN).
Let's fix up with viewpoint of zone.
