avcodec/rv10: Don't presume context to be initialized
In case of resolution changes rv20_decode_picture_header() closes and reopens its MpegEncContext; it checks the latter for errors, yet when an error happens, it might happen that no new attempt at reinitialization is performed when decoding the next frame; this leads to crashes lateron. This commit fixes this by making sure that initialization will always be attempted if the context is currently not initialized.
