flvdec: Check the avio_seek return value after reading a metadata packet
merge from libav: 585dc1aecef0371ad6f16cb3750ae2a6da9cf00a
If the metadata packet is corrupted, flv_read_metabody can accidentally
read past the start of the next packet. If the start of the next packet
had been flushed out of the IO buffer, we would be unable to seek to
the right position (on a nonseekable stream).
Prefer to clearly error out instead of silently trying to read from a
desynced stream which will only be interpreted as garbage.
