perf/UAPI: Clearly mark __PERF_SAMPLE_CALLCHAIN_EARLY as internal use
Vince noted that commit:
6cbc304f2f36 ("perf/x86/intel: Fix unwind errors from PEBS entries (mk-II)")
'leaked' __PERF_SAMPLE_CALLCHAIN_EARLY into the UAPI namespace. And
while sys_perf_event_open() will error out if you try to use it, it is
exposed.
Clearly mark it for internal use only to avoid any confusion.
