content_encoding: give a clear error on multi-member gzip
A gzip Content-Encoding response holding more than one gzip member made
curl decode the first member and then fail the transfer with a bare
CURLE_WRITE_ERROR and no hint about the cause. Detect the trailing
member and fail with a message that explains what happened.
