perf tools: Fix raw sample reading
Wrong pointer is being passed for raw data sanity checking, when parsing
sample event.
This ends up with invalid event and perf record being stuck in
__perf_session__process_events function during processing build IDs
(process_buildids function).
Following command hangs up in my setup:
./perf record -e raw_syscalls:sys_enter ls
The fix is to use proper pointer to the raw data instead of the 'u'
union.
