Because of ffio_ensure_seekback() a seek error normally should only happen if
the end of file is reached during checking for the junk run-in. Also use proper
error code.

(cherry picked from commit 49e018d6fee689af6b30b773d83f545d74b8d9aa)
We are protecting the checked buffer with ffio_ensure_seekback(), so if the
inner check fails with a seek error, that likely means the end of file was
reached when checking for the next frame. This could also be the result of a
wrongly guessed (larger than normal) frame size, so let's continue the loop
instead of breaking out early. It will end sooner or later anyway.

(cherry picked from commit b75e604fe5cd7da9ca713f20d1ade18d50319aff)
Otherwise the subsequent ffio_ensure_seekback calls destroy the buffer of the
earlier. The worst case ~66kB seekback is so small it is easier to request it
entirely.
