perf_counter: Optimize perf_counter_alloc()'s inherit case
We don't need to add usage counts for swcounter and attr usage
models for inherited counters since the parent counter will
always have one, which suffices to generate the needed output.
This avoids up to 3 global atomic increments per inherited
counter.
