selinux: fix a possible memory leak in cond_read_node()
The cond_read_node() should free the given node on error path as it's not linked to p->cond_list yet. This is done via cond_node_destroy() but it's not called when next_entry() fails before the expr loop. Signed-off-by: Namhyung Kim <namhyung@kernel.org> Signed-off-by: Paul Moore <pmoore@redhat.com>
