[PATCH 2/2] doc, mm: clarify /proc/<pid>/oom_score value range

[Michal Hocko]

From: Michal Hocko <mhocko@xxxxxxxx>

The exported value includes oom_score_adj so the range is no [0, 1000]
as described in the previous section but rather [0, 2000]. Mention that
fact explicitly.

 process should be killed in an out-of-memory situation.
