Thanks for patch.
inflate() can indeed return Z_STREAM_END when called with Z_SYNC_FLUSH, which
is not the case for deflate().

The error happens if inflate_out_filter handles flush buckets.
In some cases flush_libz_buffer returns Z_STREAM_END, which is not an error
condition.
The patch correctly handles this case.
