perf: Remove superfluous allocation error check ...
commit bfb3d7b8b906b66551424d7636182126e1d134c8 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.
