Not true really. log_error_errno() also adds ERRNO= structured fields
to the log message, the simply log_error() does not. 

Hence, if your are logging about some system error indicated in an
Exyz error code, please use log_error_errno(), regardless if you got
the errror via errno or via the return value of a function...
