netns: restore ops before calling ops_exit_list



commit b272a0ad730103e84fb735fd0a8cc050cdf7f77c upstream.

ops has been iterated to first element when call pre_exit, and
it needs to restore from save_ops, not save ops to save_ops

Fixes: d7d99872c144 ("netns: add pre_exit method to struct pernet_operations")
