Subject: [PATCH 11/16] mm/vmpressure.c: use new match_string() helper/macro

__match_string() is called on 2 static array of strings in this file. For
this reason, the conversion to the new match_string() macro/helper, was
done in this separate commit.

Using the new match_string() helper is mostly a cosmetic change (at this
point in time). The sizes of the arrays will be computed automatically,
which would only help if they ever get expanded.
