spectaclehong b13f47a4da Fix reconstruct bug when by_residual is false (#2298) 
Summary:
When I reconstruct with by_residual turned off, the distance was greatly increased.
This is because the reconstruct_from_offset function did not check if the by_residual option was off.
I fix this bug with simple if statement.
(like this https://github.com/facebookresearch/faiss/blob/main/faiss/IndexIVFPQ.cpp#L365)
