Steven Rostedt (VMware) 140acbb093 tools lib traceevent: Do not free tep->cmdlines in add_new_comm() on failure ...

[ Upstream commit e0d2615856b2046c2e8d5bfd6933f37f69703b0b ]

If the re-allocation of tep->cmdlines succeeds, then the previous
allocation of tep->cmdlines will be freed. If we later fail in
add_new_comm(), we must not free cmdlines, and also should assign
tep->cmdlines to the new allocation. Otherwise when freeing tep, the
tep->cmdlines will be pointing to garbage.
