[PATCH 7/7] perf report: Do not collect sample histogram unnecessarily

[Namhyung Kim <namhyung@kernel.org>]

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 if data type
profiling is selected and make sure the annotation has the 'struct
annotated_source' instantiated before calling symbol__disassemble().
