If you call linux_if_drops with a NULL device, then it segfaults

If you call pcap_stats() on a pcap handle that's open but not
activated, p->stats_op points to pcap_not_initialized(), so
pcap_stats() will just return an error.
That wasn't necessarily true if the activation failed, as the activate
routine might have set the op pointers early in the process and not
undone that if the activation fails; I've checked in a change to
restore the op pointers on a failed activation.
That should make this a non-issue.
