Subject: [PATCH 3/4] kernel-shark: Don't check for system name for sched events

From: Vaibhav Nagarnaik <vnagarnaik@...gle.com>

The sched tracepoint names are unique and so there is no need to check
for the subsystem name while looking up the event ID.

This helps kernel shark display the graphs correctly for trace.dat files
generated from trace collection mechanisms that don't record the subsystem.
