perf annotate: Re-add annotate_warned functionality

Setting annotate_warned to true on errors was removed in
commit ee51d85 ("perf annotate: Introduce strerror for handling
symbol__disassemble() errors") which means when 'perf annotate
--skip-missing' is used warnings are shown multiple times for the same
DSO.

Setting this again restores the original behavior of only one warning
each.
