[PATCH v1 40/48] perf list: Silence -Wshorten-64-to-32 warnings

[Ian Rogers]

The clang warning -Wshorten-64-to-32 can be useful to catch
inadvertent truncation. In some instances this truncation can lead to
changing the sign of a result, for example, truncation to return an
int to fit a sort routine. Silence the warning by making the implicit
truncation explicit.
