perf stat: Avoid uninitialized use of perf_stat_config

perf_event__read_stat_config will assign values based on number of
tags and tag values. Initialize the structs to zero before they are
assigned so that no uninitialized values can be seen.

This potential error was reported by GCC with LTO enabled.
