netns: follow return value conventions of the rest of the code

The netns code was using EXIT_SUCCESS/EXIT_FAILURE but the rest of the ip
code used -1 explictly, so change to follow convention. Also, certain types
of errors like fork failure should abort a batch operation, rather than just
returning an error.
