The commit b97511c5bc94 ("perf tools: Add overhead/overhead_children
keys defaults via string") moved initialization of column headers but it
missed to check the sort__mode.  As 'perf diff' doesn't call
perf_hpp__init(), the setup_overhead() also should not be called.

perf diff: Fix duplicated output column

The commit b97511c5bc94 ("perf tools: Add overhead/overhead_children
keys defaults via string") moved initialization of column headers but it
missed to check the sort__mode.  As 'perf diff' doesn't call
perf_hpp__init(), the setup_overhead() also should not be called.
