    libxc/unlz4: always set an error return code on failures
    
    "ret", being set to -1 early on, gets cleared by the first invocation
    of lz4_decompress()/lz4_decompress_unknownoutputsize(), and hence
    subsequent failures wouldn't be noticed by the caller without setting
    it back to -1 right after those calls.
