Comment 1 for bug 1851499

Problem is more complex. When receive incomplete frame, decompression context need to be reset with LZ4F_resetDecompressionContext (added in lz4 1.8.0).

I add simple port

void LZ4F_resetDecompressionContext(LZ4F_dctx* dctx)
{
    dctx->dStage = dstage_getHeader;
    dctx->dict = NULL;
    dctx->dictSize = 0;
}

And with first patch problem was solved.
