[PATCH] mm/oom: fix pgtables units mismatch in Killed process message

[Ilya Dryomov]

pr_err() expects kB, but mm_pgtables_bytes() returns the number of
bytes.  As everything else is printed in kB, I chose to fix the value
rather than the string.

Before:

[  pid  ]   uid  tgid total_vm      rss pgtables_bytes swapents oom_score_adj name
...
[   1878]  1000  1878   217253   151144  1269760        0             0 python
...
Out of memory: Killed process 1878 (python) total-vm:869012kB, anon-rss:604572kB, file-rss:4kB, shmem-rss:0kB, UID:1000 pgtables:1269760kB oom_score_adj:0

After:

[  pid  ]   uid  tgid total_vm      rss pgtables_bytes swapents oom_score_adj name
...
[   1436]  1000  1436   217253   151890  1294336        0             0 python
...
Out of memory: Killed process 1436 (python) total-vm:869012kB, anon-rss:607516kB, file-rss:44kB, shmem-rss:0kB, UID:1000 pgtables:1264kB oom_score_adj:0

Fixes: 70cb6d267790 ("mm/oom: add oom_score_adj and pgtables to Killed process message")
