David Ahern 8fb598e5a3 perf trace: Fix comm resolution when reading events from file
Task comm's are getting lost when processing events from a file. The
problem is that the trace struct used by the live processing has its
host machine and the perf-session used for file based processing has its
host machine.  Fix by having both references point to the same machine.
