perf hist: Only allocate callchain_node if processing callchains
The struct callchain_node size is 120 bytes, that are never used when there are no callchains or '-g none' is specified, so conditionally allocate it, reducing sizeof(struct hist_entry) from 210 bytes to only 96, greatly speeding the non-callchain processing.
