fix darshan-job-summary reporting spurious total bytes written
Fixes a little typo error that was causing the I/O performance estimate (at the top of the job summary PDF) to report the wrong total bytes transferred. The correct value was getting clobbered if STDIO data was present. The actual performance reported was always correct, but might as well report the correct numerator used to calculate that performance.
before_fix.darshan.pdf is the resulting PDF without this fix applied
after_fix.darshan.pdf is the resulting PDF after this fix is applied
before.darshan is a sample log that was used to generate both PDFs. You can calculate the bytes moved by hand to verify the fix.
