Subject: [PATCH] Fix core and policy args count

The core and policy args count includes both the keys and values already, so does not need to be
multiplied * 2.

Ref: In https://www.kernel.org/doc/Documentation/device-mapper/cache.txt, core args and policy arg count
are specifed as "must be even".
