perf annotate: Fix data type profiling on stdio

The loop in hists__find_annotations() never set the 'nd' pointer to NULL
and it makes stdio output repeating the last element forever.  I think
it doesn't set to NULL for TUI to prevent it from exiting unexpectedly.
But it should just set on stdio mode.
