pututxline: Don't set errno=0 in subfunctions.
The functions utx_active_add(), utx_active_remove(), utx_lastlogin_add() and utx_log_add() set errno to 0 if they are successful. This not only violates POSIX if pututxline() is successful, but may also overwrite a valid error with 0 if, for example, utx_lastlogin_add() fails while utx_log_add() succeeds. Reviewed by: ed
