perf/x86/amd/uncore: Turn amd_uncore_ctx events into a flexible array
The events pointer was kzalloc_node()'d immediately after the parent
struct allocation, with the count (pmu->num_counters) trivially
available beforehand. Move events to the struct tail as a flexible
array member and fold the two allocations into a single kzalloc_node()
with struct_size(), dropping the separate kfree(ctx->events) in the
free path.
