    Initialize the trans structure fields to values unused by perf samples
    
    On newer 4.14 kernel operf was crashing because the kernel commit
    1d953111b648e ("perf/core: Don't report zero PIDs for exiting tasks")
    made perf samples have TID/PID of -1 for exiting processes.  OProfile
    used this same value internally to indicate the that field had not
    been initialized.  As a result operf would incorrectly attempt to run
    some bookkeeping code due to an invalid match. The initialization of
    the trans tgid field is now changed to a value that is unsed by the
    perf samples to ensure that these invalid matches do not occur.
