Subject: [PATCH 13/15] libtracefs: Close dir in the error path in
tracefs_system_events()
In tracefs_system_events(), we don't close dir if add_list_string()
fails. At this point, just breaking out of the loop fixes that.
Fixes a RESSOURCE_LEAK error (CWE-772)

Fixes: 056a177e1d686 ("libtracefs: Restructure how string lists work")
