As a followup to bug#4726, handle a write size of zero for all transmission paths as error. This matches other parts of the code base, such as fd_write_all.

Neither the gnutls nor the POSIX documentation mentions a write size of
zero specifically. It is apparently up to each application to decide
what to do with such short write results. So in case of Claws Mail,
consider it an error in all cases.
