perf scripts python: cs-etm: Restore first sample log in verbose mode

[PATCH] perf scripts python: cs-etm: Restore first sample log in verbose mode

Posted by James Clark 1 month, 2 weeks ago

The linked commit moved the early return on the first sample to before
the verbose log, so move the log earlier too. Now the first sample is
also logged and not skipped.

Fixes: 2d98dbb4c9c5 ("perf scripts python arm-cs-trace-disasm.py: Do not ignore disam first sample")
