[PATCH 6/6] perf report: Do not collect sample histogram unnecessarily

The data type profiling alone doesn't need the sample histogram for
functions. It only needs the histogram for the types.

Let's remove the condition in the report_callback to check the data type
profiling and make sure the annotation has the annotated_source before
calling symbol__disassemble().
