perf tests pmu: Initialize all fields of test_pmu variable

Instead of explicitely initializing just the .name and .alias_name,
use struct member named initialization of just the non-null -name field,
the compiler will initialize all the other non-explicitely initialized
fields to NULL.

This makes the code more robust, avoiding the error recently fixed when
the .alias_name was used and contained a random value.
