librte_pmd_pcap driver was opening the pcap/interfaces only at init time and closing them only when the port was being stopped. This behaviour would cause problems (leading to segfault) if the user closed the port 2 times. The first time the pcap/interfaces would be normally closed but libpcap would throw an error causing a segfault if the closed pcaps/interfaces were closed again. This behaviour is solved by re-openning pcaps/interfaces when the port is started (only if these weren't open already for example at init time).
