Display transaction id correctly in log

The transaction id is a 64-bit integer. A call to the
HdfsLogger::log was incorrectly coded with a %d format
string, leading to truncation or interpretation as a
negative number. This change allows correct logging
of transaction id by using %ld in the format string.
