At SUSE12 SP3, we hit a case where ovs-check-dead-ifs tries to read an entry in /proc/<pid>/fd/<some fd> but hangs forever. The pid is a qemu-system-x86_64 process and we suspect it's an issue related to qemu, not ovs. As a result, force-reload-kmod hangs and OVS bridge never gets restarted. This patch adds a timeout of 5-seconds to ovs-check-dead-ifs.
