volser: Remove debugging log messages

volser: Remove debugging log messages

While the -log option to volserver is supposed to print additional log
information, it shouldn't spam the log with useless data. Remove some
of the log lines that are really more "debug" information, so we log
the same amount of information as in the 1.4 series.
