When in live-pcap mode, if the sniffed interface went down and up again,
Suri would enter an infinite and keep running, while not registering new
events. This fixes that behavior by allowing Suri to retry to open the
pcap in case of a retry on an already activated capture
('PCAP_ERROR_ACTIVATED').
This change is based on Zhiyuan Liao's work.
