[ Upstream commit d3c45824ad65aebf765fcf51366d317a29538820 ]

The failure to retrieve post-op attributes has no bearing on whether or
not the clone operation itself was successful. We must therefore ignore
the return value of decode_getfattr() when looking at the success or
failure of nfs4_xdr_dec_clone().
