Subject[PATCH 15/23 v3] tools lib traceevent: Fix reporting of unknown SVM exit reasons
From: Jan Kiszka <jan.kiszka@siemens.com>

On AMD, exist code -1 is also a possible value, but we use it for
terminating the list of known exit reasons. This leads to EXIT_ERR
being reported for unkown ones. Fix this by using an NULL string
pointer as terminal.
