qemuProcessReportLogError: Remove unnecessary math for max error message

Now that error message formatting doesn't use fixed size buffers we can
drop the math for calculating the maximum chunk of log to report in the
error message and use a round number. This also makes it obvious that
the chosen number is arbitrary.
