#3808: Seeking in flv with video stream disabled fails

Seeking in flv with video stream disabled (i.e. st->discard =
AVDISCARD_ALL) does not work. The seek call apparently succeeds, but after
that no packets can be read. The same works if the video stream is
enabled.
I couldn't reproduce this with the ffmpeg command line utility. I suspect
it's because "-ss" seeks the file _before_ the unneeded streams are
disabled.
Sample: youtube-dl http://www.arte.tv/guide/de/049446-000/das-buch-der-
madrigale
(Probably any flv file does it.)
I tested with a recent git head, but I know that the problem probably
existed for ages.
