[PATCH 3/4] lib-compression: istream-zstd - Guard against no-progress loop in read

If ZSTD_decompressStream() returns with neither input consumed nor
output produced, the read loop would spin indefinitely. Add a check
after each call: if input.pos is unchanged and output.pos is zero,
treat it as a corrupt stream (EIO).
