[0/2] perf cs-etm: Track exception level fixups

Message

A couple of changes related to edge cases since commit 8d3031d39fe8
("perf cs-etm: Track exception level").

I think the second one is low risk seeing as any path requiring a thread
leading up to adding to the histogram would already have been crashing.
Maybe the thread check could also be added to hist_entry_iter__add()
although other users of it don't seem to have the same issue, and there
is another use of al.thread above in builtin-report.c so it's probably
ok where I've added it.

Applies to perf-tools-next/perf-tools-next (929ff679b69)

  perf report: Don't add to histogram when there is no thread found
