[PATCH v3 10/15] perf python: Zero initialize perf_data in pyrf_data__init

| Message-ID | <[email protected]> |
Replace path clearing with memset so the entire struct is zeroed,
preventing uninitialized fields from causing errors later.
Fixes: 4cd0142f7dec ("perf python: Add wrapper for perf_data file abstraction")
