The error path frees all side data, but forgets to reset the side data
count. This can blow up later in av_frame_unref() and free_side_data().

When matroska_execute_seekhead() is called, it goes through the list of
seekhead entries and attempts to read elements not read yet. When doing
this, the parser can find further SeekHead elements, and will extend the
matroska->seekhead list. This can lead to a (practically) infinite loop
with certain broken files. (Maybe it can happen even with valid files.
The demuxer doesn't seem to check correctly whether an element has
already been read.)
Fix this by ignoring elements that were added to the seekhead field
during executing seekhead entries.
This does not fix the possible situation when multiple SeekHead elements
after the file header (i.e. occur after the "before_pos" file position)
point to the same elements. These elements will probably be parsed
multiple times, likely leading to bugs.
Fixes ticket #4162.
