perf/x86/intel/uncore: Clean up hotplug conversion fallout
The recent conversion to the hotplug state machine kept two mechanisms from
the original code:
1) The first_init logic which adds the number of online CPUs in a package
to the refcount. That's wrong because the callbacks are executed for
all online CPUs.
Remove it so the refcounting is correct.
2) The on_each_cpu() call to undo box->init() in the error handling
path. That's bogus because when the prepare callback fails no box has
been initialized yet.
Remove it.
