trace-cmd lib: Prevent possible memory corruption in add_plugin_file()
If strdup() fails the error path access original address of
pdata->files after it has been dereferenced. Make sure that
pdata->files contains the up-to-date pointer before calling calling a
function that could fail.
This was flagged as resource leak (CWE-772) because ptr isn't freed
in that scenario, but there is something worse going on that the
static analysis missed.
