[PATCH 1/2] tracing, function_graph: fix micro seconds notation in comment

[byungchul.park@lge.com]

From: Byungchul Park <byungchul.park@lge.com>

Usually, "msecs" notation means milli-seconds, and "usecs" notation
means micro-seconds. Since the unit used in the code is
micro-seconds, the notation should be replaced from msecs to usecs.
This confusing notation prevents us from understanding the code
correctly.
