Fixed case when netsniff fails if there is already existing monX device
while generating.

+int device_ifindex(const char *ifname)

+       if (unlikely(index <= 0))

This test should be < 0 only as ifindex 0 would mean to
capture on "any" device.

So starting netsniff-ng w/o any arguments would not work
anymore otherwise, fix up:

+               panic("Cannot get ifindex from device!\n");
+
+       return index;
+}

Cheers,
Daniel
