[PATCH ulogd2 v2 v2 10/34] src: remove `TIME_ERR` macro

[Jeremy Sowden <jeremy@azazel.net>]

The `TIME_ERR` macro is used to check the return value of time(2).
However, two of the definitions of it are never used.  The third is used
to check the return value of `time(NULL)`.  However, time(2) with a
`NULL` argument can never fail, so we don't need to perform the check.
