Ulrik 95314cd7c5 avformat/flacdec: Return correct error-codes on read-failure ...

Forward errors from `avio_read` directly. When `avio_read` sees EOF before
expected bytes can be read, consistently return `AVERROR_INVALIDDATA`

We used to return `AVERROR(AVERROR_INVALIDDATA)` when failing to read
metadata block headers. `AVERROR_INVALIDDATA` is already negative, so
wrapping in `AVERROR` leads to double-negation.

We used to return `AVERROR(EIO)` when failing to read extended metadata.
However, many times, the IO-layer is not at fault, the input data is simply
corrupted (truncated), so we return `AVERROR_INVALIDDATA` here as well.
