maildir: drain limit channel on parse error when sorting
Commit 155f0c3f28a1 ("maildir/sort: get MessageInfos in parallel") added
parallel parsing of maildir messages. The parsing is limitted to 2x the
number of CPUs using a buffered channel. The channel is drained at the
end of the parsing, however it is not drained if a parse error is
encountered. With enough errors, this can lead to a deadlock.
Drain the channel when an error occurs.
Fixes: 155f0c3f28a1 ("maildir/sort: get MessageInfos in parallel")
