Jiri Olsa 68447d694f perf: Remove superfluous allocation error check ...

commit bfb3d7b8b9 upstream.

If the get_callchain_buffers fails to allocate the buffer it will
decrease the nr_callchain_events right away.

There's no point of checking the allocation error for
nr_callchain_events > 1. Removing that check.
