ipnetns: fix ip batch mode when using 'netns exec'

Since commit a05f6511f543, ip batch mode is broken when using 'netns exec' cmd.

When WIFEXITED() returns true, it means that the child exited normally, hence
we must not call exit() but just returns the status. If we call exit, the next
commands in the file file are not executed.
If WIFEXITED() returns false, we can call exit() because it means that the
child failed.

This patch partially reverts commit a05f6511f543.
